leonarski_fandClaude Opus 5	fb55645b81	Revert "rugnux: fit the profile radius from the strongest spots too" ... Reverts the profile-radius part of 457b1bfd1; the comparison-script and mosaicity-column changes from that commit are kept. The cap was validated on the rotation battery, which cannot test it: the profile radius feeds `ewald_dist_cutoff` in IndexAndRefine, and that is read only by the STILLS predictors (BraggPrediction/BraggPredictionGPU). The rotation predictors gate on the mosaicity window instead and never look at it. So "no space-group changes, 36 of 37 crystals bit-identical" showed the quantity is inert for rotation, not that capping it is safe - and the one regime where it does act was never exercised. Validating it needs the serial-stills battery, which is a much larger exercise. Until then the arbitrary constant is not worth carrying in a code path nobody measured.

leonarski_fandClaude Opus 5	5eb386e333	docs: describe the per-frame geometry smoothing ... Goes in §10.3 next to the per-frame scale and mosaicity smoothing, since it is the same mechanism applied for the same reason, and trims the changelog line to one sentence.

leonarski_fandClaude Opus 5	017f64690c	rugnux: smooth the per-frame geometry before scaling ... Geometry is re-refined independently on every frame, against that frame's spots alone - as few as a dozen on a sparse crystal, where XDS fits its equivalent to about sixty times more data. Measured over ten datasets the per-frame orientation carries two components: a slow drift that is real, with rugnux and XDS agreeing to R^2 0.83-0.88 on the two crystals that genuinely slip by 1.5 and 0.54 degrees, and a fast jitter that is fit noise, scaling with spots-per-frame at exponent -0.79 where counting noise alone would give -0.5. The jitter is worth 1-8% on merged intensities, 24% on the sparsest crystal. It cannot be fixed by refining less. Turning per-image refinement off entirely loses six space groups and a whole crystal, and even a 624-spot-per-frame crystal collapses; dropping the beam-centre terms holds the space groups but is worse on 31 of 37 crystals. The freedom is earning its keep, so keep it and suppress only the band that cannot be physical - a crystal does not re-orient and snap back from one frame to the next. So smooth the orientation in frame order after integration and recompute each partial's delta_phi, and hence its partiality, from the smoothed lattice. Batching at integration time was not an option: frames are processed independently and the online path depends on that. This runs before the GPU upload, so the device path picks it up with no separate kernel. The window is chosen per dataset by leave-one-out cross-validation, because the two components vary far too much for one number - drift spans 0.018 to 1.288 degrees and jitter 0.005 to 0.221, so any fixed window over-smooths one crystal while under-smoothing another. Chosen windows range from +-1 to +-20 frames. It is capped: cross-validation scores how well neighbours predict a frame's orientation, which on a barely-drifting crystal keeps improving with width, but the per-frame fit is also absorbing a real per-frame systematic and smoothing too wide destroys it - uncapped, one crystal chose +-60 and lost 16% of its ISa. Battery over 37 crystals: space groups unchanged at 34 matching XDS, R_meas better on 31 and worse on 6, low-resolution R_meas 30/7, ISa 26/10, high-resolution CC1/2 23/12.

leonarski_fandClaude Opus 5	457b1bfd1d	rugnux: fit the profile radius from the strongest spots too ... Same defect as the mosaicity in 2c94f3013, in the same file's sibling fit. The profile radius is an RMS of the excitation error over whatever spots were kept, and weaker spots sit further off the Ewald sphere, so it grows with the depth of the list: measured over a 150 -> unlimited spot budget it rises ~60%, and on a clean dataset as much as on a hard one, so this is general rather than something one awkward crystal provoked. That made it a function of --max-spots, which is an indexing budget, rather than of the crystal. Its one consumer treats it as a membership gate (ewald_dist_cutoff is twice it) where reflections at the cutoff carry near-zero partiality and are removed downstream anyway, so the integrated data barely notices: with the mosaicity already pinned, the partial count moves 0.2% across a 34% change in the radius. It is also reported per image as a diagnostic, though, and a number that slides with an unrelated setting is misleading to anyone comparing two runs - and it would stop being benign the moment anything used it as a width rather than a gate. Battery over 37 crystals: no space group changes, 36 of 37 bit-identical, no failures, one crystal marginally better. Also in the comparison script: report XDS's mosaicity next to rugnux's. XDS has two and they are not interchangeable - CORRECT.LP's REFLECTING_RANGE_E.S.D. is post-refined, while INTEGRATE.LP's per-batch SIGMAR is its integration-stage estimate, and the two differ by up to 2.3x. The XDS cell now prints both as postrefined|MLE so a per-image estimate is compared against the one measured the same way. Fixes a scoping bug in the same addition where every crystal read the last directory's INTEGRATE.LP. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-04 10:52:30 +02:00
leonarski_fandClaude Opus 5	2c94f3013e	rugnux: fit the mosaicity from the strongest spots only ... The per-image mosaicity MLE ran over the whole indexed spot list, so it rode on --max-spots, which is an indexing budget. A spot is detected when I_full * R(tau) clears the finder threshold, so selecting by intensity censors on R(tau): a deeper list holds proportionally more large-|tau| partially recorded spots and the fit widens with it. Raising the budget 250 -> 1000 widened sigma_M 0.059 -> 0.075 deg on a rotation dataset whose measured rocking width says 0.054. That is not cosmetic. An over-wide mosaicity mis-states every partiality in scaling: forcing the mosaicity across that range moved the merge error model from b 0.039 / ISa 26 to b 0.167 / ISa 6, and the space-group search lost a genuine 422 with it, merging the crystal in 222 instead. Cap the fit at the strongest 250 spots. FilterSpotsByCount leaves the list strongest-first, so this selects exactly the spots a smaller --max-spots would, and the mosaicity becomes invariant: 0.0538 deg at 250, 500, 1000 and 2000 spots, with the correct space group at each. Trimming or down-weighting the tau tail does not work - the censoring is multiplicative in R(tau), so it widens the whole distribution rather than adding a tail. Battery over 37 crystals: exactly one change, the demoted crystal repaired (33 space groups matching XDS -> 34). 23 of 37 are bit-identical, never reaching 250 spots. Unaffected elsewhere: the default spot count is 250, and stills have no goniometer so they return before the fit.

leonarski_fandClaude Opus 5	f25fea7024	rugnux: keep 1000 spots per image instead of 250 ... Offline reprocessing is not bound by the online spot budget, and the cap is applied at the end of SpotAnalyze, so it is exactly the spot list the indexer and the per-image refinement see. jfjoch_viewer already sends 1000, so the two front ends now agree on the same file. Measured as a paired A/B over the 37-crystal rotation battery, de novo, with the resolution and Friedel setting matched to the XDS reference, both arms from the same binary bar this constant: R_meas low shell 16 better 0 worse 19 unchanged R_meas 14 better 4 worse 17 unchanged ISa 14 better 6 worse 15 unchanged CC1/2 6 better 3 worse 26 unchanged Low-resolution R_meas is a clean sweep. Around half the battery is bit-identical: those frames never reach 250 spots, so the cap never bound. Wall clock is unchanged (10m00s vs 10m44s, uncontrolled for page cache). Known cost, and the reason this is its own commit: one crystal in the battery reproducibly loses symmetry, tetragonal 422 -> orthorhombic 222, doubling its asymmetric unit. Its R_meas and ISa "improve" there, but that is what merging in too low a symmetry always does, and the lower symmetry then admits a merohedral indexing ambiguity. An intermediate cap of 500 demotes it too, so it buys none of the safety. This is the known point-group-decision-moves-with-data-amount fragility of the space-group search rather than an argument for starving the indexer of spots - the search is the thing to fix.

leonarski_fandClaude Opus 5	2473e03cf7	rugnux: default --spot-sigma to 4.0, the value the viewer already uses ... The two front ends disagreed on the fixed-threshold spot finder: rugnux started from 3.0, jfjoch_viewer from the SpotFindingSettings default of 4.0, so the same file processed either way could give different spots. Inert on the default path - the adaptive finder derives its threshold from each image's own per-resolution-ring noise and never reads signal_to_noise_threshold (only ImageSpotFinderCPU/GPU and DetModuleSpotFinder do). It changes behaviour only under --no-adaptive-spots, and there it now matches the viewer. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 22:07:58 +02:00
leonarski_fandClaude Opus 5	cd0c43c65c	docs: add the packaging and documentation work to the rc.161 change list ... Covers the Debian package rename and the DKMS scripts, the writer's --verbose, the version plumbing, and the documentation pass - the release-contents page, the corrected repository URLs and package names, and the rugnux, viewer and writer pages.

leonarski_fandClaude Opus 5	cfcb84aece	docs: bring the tool pages back in line with the programs ... rugnux gained --model - R-free and 2Fo-Fc/Fo-Fc maps against an atomic model, and with it the resolution of the enantiomorph and of a merohedral indexing ambiguity - without the page ever mentioning it. It was the only option missing; the two lists now agree in both directions, checked against the usage the binary prints. The viewer page still said results are never saved and that no Windows package exists. Both have been false for a while: the Processing panel runs full rugnux jobs on the open dataset, writes _process.h5 and the merged reflections, registers each run as a selectable view so runs can be compared, and can hand out the equivalent command line for a cluster; and the installer is published with every release. The mask menu also loads TIFFs now, and the View menu has layout presets. The writer page documented -R for the root directory, which is the back-compatibility alias for -d, and an HTTP status interface that no longer exists - status reaches the broker over the writer notification socket, and a writer is stopped with a signal. The test page pointed at .gitlab-ci.yml and at jfjoch_offline_process, which is not a binary any more; the CrystFEL fixture pointed at HDF5DatasetWriteTest, which is not either. The broker page linked ../broker/redoc-static.html, which MyST resolved by copying the 700 kB file into _downloads/ rather than using the copy already in _static.

leonarski_fandClaude Opus 5	46930142dd	docs: write down what a release ships ... Nothing said what is in a release or what it needs of the machine it lands on: that the Linux binaries are built -march=x86-64-v3 and the Windows ones /arch:AVX, so each has a CPU floor; that the portable .tgz is built on RHEL 8 for its glibc; that the Windows installer is MSVC (Visual Studio 2026), CUDA 13.3, Qt 6.11 and carries the Qt runtime; and above all what the CUDA variants need. Only cuFFT is linked dynamically, and it has no link-time dependency on the driver library, so a CUDA build starts on a machine with no NVIDIA GPU at all and falls back to the CPU path - as long as cuFFT can be loaded, which the .tgz and the installer arrange by shipping it and the distribution packages arrange through the distribution's own CUDA packages. Collected into a new page rather than scattered over the install instructions. The repository page had the RHEL 9 rows pointing at el8 paths under the wrong slsdet number, no rows at all for the two slsdet9 repositories the pipeline uploads, a driver package named jfjoch-driver where it is jfjoch-driver-dkms, and a note that RPMs are unsigned from before the pipeline started uploading them with sign=true. The FPGA page had a paragraph that stopped mid-sentence, in the middle of a link, and a section describing a firmware build triggered by commit message. The firmware is stable and carried from version to version now. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 20:53:19 +02:00
leonarski_fandClaude Opus 5	8712160adb	scripts: point the generated Python client at gitea, and make the scripts runnable ... The openapi-generator invocation still passed --git-host=git.psi.ch and a user id of jungfraujoch, from before the move to gitea.psi.ch/mx/jungfraujoch. Those properties are not cosmetic: they become the source URL in the generated README and pyproject, so the published client documentation - docs/python_client/README.md, which is copied out of the generated tree - told readers to pip install from a host that no longer answers. Regenerating with the corrected flags changes those two lines and nothing else, verified against the committed tree. update_version.sh, make_doc.sh and gen_python_client.sh were all mode 644, so the "run update_version.sh" the documentation asks for fails on the shebang. CMake and the CI both work around it by invoking them through bash. make_doc.sh builds a throw-away venv in the working tree and deletes it on the last line, which set -e skips whenever pip or sphinx fails - so a failed docs build left tmp_venv/ behind. Delete it from a trap instead, and ignore it along with the default output directory and the sdist directory gen_python_client.sh creates.

leonarski_fandClaude Opus 5	b6c4a59d69	docs: record the stored-format break, and say how the adaptive finders actually accumulate ... The per-image image-scale B factor was dropped from the CBOR stream and from the written HDF5, which is a change for anything reading those files, but the changelog listed it only under the OpenAPI breaking changes. The GPU adaptive finder test claimed both finders sum the rings in double. The CPU one does; the GPU one stages a block's contribution in float before reducing across blocks in double, deliberately, to keep the hot loop's shared footprint down. Say so, and say what follows from it - detection compares integer pixel values, so a threshold that crosses an integer flips every pixel of that value in the ring at once.

leonarski_fandClaude Opus 5	bec7e2e922	image_preprocessing: fuse the bitshuffle inverse with preprocessing, and verify the decode ... The device decoder was byte-exact on every valid input - 994 production-compressed images, 927 hand-built LZ4 blocks covering engineered (offset, matchlen) pairs across the overlap branch boundary, 18000 repeat decodes, sanitizer-clean - and an audit against LZ4_decompress_generic could not construct a valid block it mis-decodes. What it did not do was notice when the input was NOT valid, and that mattered more than it looks: the decode buffers are reused frame to frame, so a block that stopped early left the PREVIOUS image in place, and in the bitshuffled layout the untouched tail is the most significant byte-plane. A corrupt chunk therefore did not look like a missing corner. It looked like thousands of real pixels several powers of two too bright, fed to spot finding with no diagnostic, where the host decoder had raised an error. So the kernel now flags a block that fails to reach its declared length while consuming exactly its payload, and the host turns that into an exception once the caller has synchronised. Reads are clamped against the end of the payload as well as the output, both length chains are bounded exactly as read_variable_length bounds them, the two offset bytes are bounded, and LZ4's parsing restrictions are enforced. On the host side a block size that is not a multiple of 8 elements is rejected (it made the un-transpose read uninitialised shared memory), the block count is bounded by what the chunk could hold before it becomes an allocation (twelve header bytes could demand hundreds of MB of pinned memory, permanently, per worker), trailing bytes are rejected, and the stream is synchronised before any throw that happens after work is queued. An image of fewer than 8 elements is all verbatim tail and now decodes rather than throwing. When the device route fails for any reason the host decoder gets its turn, so it costs speed rather than the acquisition. The lanes cooperate on the copies and a later match can read bytes another lane wrote, which since Volta needs an explicit __syncwarp(); it worked only because ptxas happened to reconverge at the post-dominator. The prototype's offset == 1 and power-of-two fast paths are also restored - the shipped kernel ran a runtime modulo, an emulated 32-bit division per output byte, on the path its own comment calls the common case. The un-transpose is now fused with preprocessing. One thread owns one group of 8 elements across every byte-plane, so once it has transposed its 8 bytes out of each plane it holds 8 complete elements and emits 8 finished int32 pixels with the mask, the error marker, the saturation cap and the statistics applied. The decompressed image is never materialised: 0.623 -> 0.411 ms/frame at 18 Mpx, 0.523 -> 0.340 with 8 concurrent workers. Staging nothing in shared memory also drops the 48 kB ceiling, which had made any file whose bitshuffle blocks exceed it a hard failure; 64 kB blocks now decode. gpu_compressed is sized from the chunk with grow-on-demand instead of from the uncompressed size - it was reserving ~73 MB per worker to hold ~4 MB. Measured on a 1630x1553 uint32 rotation set at -N 32, peak GPU memory falls 3756 -> 3084 MiB; the same model gives ~144 MB per worker on an 18 Mpx frame. Decoding on the device also stopped reporting a decompression time, which blanked the broker's compression plot trace and filled /entry/profiling/compressionTime with NaN. The decoder brackets the decode with CUDA events and reports it again. Tests: a differential fuzz suite against the CPU decoder - incompressible and highly compressible data, engineered offsets, a size sweep hitting every rem%8 value twice, all six element sizes, an 18 Mpx frame, decoder reuse, concurrency, hand-built LZ4 blocks across the overlap boundary, 26 foreign bitshuffle block sizes from 128 B to 64 kB, corrupt payloads and malformed containers, with a coverage report that proves which LZ4 paths were reached rather than assuming it. Plus the fused path held byte for byte against ImagePreprocessorCPU, statistics included, and against the host-upload path on the same frame. Battery: 37 crystals, every merged number identical to the host-decode run. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 14:13:55 +02:00
leonarski_fandClaude Opus 5	47277674fa	docs: split the breaking API changes out of the rc.161 change list ... Earlier releases put breaking changes in their own paragraph after the bullets (rc.139, rc.29) rather than as one item among them. Follow that: the OpenAPI changes now sit under their own heading below the list, with the client-side action in the lead line, and are listed one per change instead of run together.

leonarski_fandClaude Opus 5	737cbde3ff	docs: tighten the changelog and the decoding section for release ... The rc.161 changelog had grown entries several hundred words long and listed the same area three or four times over. Collapse them by subject - spot finding, resolution limits, space-group search, scaling, performance, correctness - and hold each to one line, keeping the actionable detail in the breaking API entry. Add the performance work that had not been written up: device-side image decoding and the parallel first-pass candidate-cell refinement. Section 0 of the CPU analysis document was the longest thing in it after two core algorithm sections, and most of that was a profiling narrative and the measurements that motivated the change rather than a description of what runs. Cut it to the two kernels, the host-side block scan and the fallback rule. The attribution stays; it is also in the reference list.

leonarski_fandClaude Opus 5	6e4c0ce202	image_preprocessing: decode bitshuffle+LZ4 on the GPU ... The pipeline decompressed each image on the host and uploaded the result. On an 18 Mpx rotation dataset that made the host-to-device copy the bottleneck of the whole per-image loop: nsys puts the copies at 78% of the loop against 39% for every kernel combined - 3600 transfers of 72.4 MB - and they ran at only 12.5 GB/s of an available 27-28 because the host-side decompression was itself saturating host memory bandwidth. The GPU was mostly waiting. So the compressed chunk goes across instead, about 4 MB rather than 72 MB, and is decoded on the device. That removes the transfer and the host decompression that was throttling it, in one change. Measured on an idle machine, a run goes from 45.11 s to 24.97 s - 1.81x - with the merged output unchanged. THE APPROACH IS JON WRIGHT'S (ESRF): "Experiences with GPU decompression for bitshuffle + LZ4 data", HDF5 User Group 2021, and github.com/jonwright/ bslz4decoders. The kernels here are ours, but the idea and the demonstration that it is worth doing are his. Cited in docs/ACKNOWLEDGEMENT.md and in the new section 0 of docs/CPU_DATA_ANALYSIS.md. Two kernels mirror the CPU decoder. LZ4 runs one WARP per bitshuffle block: every lane parses the same sequence stream (a broadcast read, no divergence) and the literal and match copies are split across the 32 lanes so the stores coalesce; an overlapping match is treated as a pattern of period offset sourced from bytes that already precede the write position, which keeps it parallel rather than a serial byte loop. One thread per block instead measured 13x slower. The bitshuffle inverse then un-transposes each byte-plane through shared memory and interleaves the planes back into elements. Only BSHUF_LZ4 is decoded on the device. The zstd variants have no device decoder, and neither has an uncompressed or float image; Supports() returns false for those and the caller decompresses on the host exactly as before. The fallback is explicit, so a format we cannot decode on the device is a slower path and never a wrong answer. Tests hold the device decoder against the CPU one byte for byte, on data from the production compressor, for every element size the detectors emit - including the 8-bit DECTRIS modes, which take bitshuf_decode_block's separate elem_size == 1 branch - plus a many-block frame, the formats it must decline, and malformed containers, which must throw rather than run off a buffer. Battery: 37 crystals, no failures, identical to the host-decode run. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-03 00:16:36 +02:00
leonarski_fandClaude Opus 5	d55f3257ed	ci: regenerate the published API artefacts, and build Linux with LTO ... update_version.sh had not been run for the adaptive spot-finding schema change. Running it leaves the C++ server model and the TypeScript client byte-identical to what the generators produced directly, but it also regenerates two artefacts the direct calls do not touch and which are tracked: the Python client's published documentation and the Redoc bundle. Both now carry adaptive_threshold and false_pixels_per_frame. LTO joins -march in the CI flags, which is why MARCH_CMAKE_FLAGS is now LINUX_CMAKE_FLAGS - it no longer describes only the architecture. Measured on rugnux against an otherwise identical build: 7-10% fewer retired instructions and a 9% smaller binary, but only ~1.5% off the wall clock, because the pipeline is GPU- and I/O-bound. It costs about 3x on an incremental rebuild (9.8 s -> 30.1 s for one file plus link), so it stays out of CMakeLists and out of a developer's edit cycle: CI builds from scratch and ships the result, paying the link once. It links against CUDA with no special handling, and both CI images already put gcc-toolset-13 on PATH, which -flto=auto requires. MSVC is left alone: its LTO is a different flag (/GL + /LTCG) and nothing here measured it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-02 20:21:50 +02:00
leonarski_fandClaude Opus 5	90ab67f376	broker: expose adaptive spot finding over the API ... The self-calibrating detection threshold was reachable from rugnux and the viewer but not online: spot_finding_settings carried no adaptive_threshold, so the receiver always ran the fixed-threshold finder and the fused GPU engine sat unused behind it. adaptive_threshold and false_pixels_per_frame are now part of the schema, both optional so an existing client that sends neither is unaffected, wired through OpenAPIConvert in both directions and surfaced in the frontend panel, where turning the mode on greys out the count threshold it replaces and reveals the operating point it uses instead. The C++ server model and the TypeScript client are regenerated from the spec; the Python client is generated but not tracked. Enabling it is REFUSED where spots are found on the FPGA - the JUNGFRAU and EIGER workflows - rather than accepted and ignored, because a detection setting that silently had no effect cannot be told apart from one that did. The DECTRIS/SIMPLON workflow, which analyses images in software, accepts it. Verified against a running broker: adaptive_threshold true is rejected with that message and leaves the stored settings untouched, while false and omitted both succeed. It stays off by default online, unlike rugnux and the viewer. The broker serves both workflows and the default has to be the one that works on either.

leonarski_fandClaude Opus 5	e7be5447d3	receiver: stop copying every frame back from the device on the Lite path ... The Lite workflow built its analysis with the fused GPU engine disabled, which is also what decides whether the preprocessed image is copied device-to-host after every frame. So on a machine with a GPU the online path was moving the whole image back - 72 MB on a large detector, every frame, per worker - for a host reader that does not exist on that path. It was left off deliberately when the fused engine was added, to keep the online path unchanged in that commit, and never revisited. Nothing depends on it: the FPGA workflow uses a different analysis class, and strong-pixel values are read through a device gather rather than from the host image. Turning it on changes no result, and cannot: adaptive detection is unreachable online, because the REST schema exposes no way to enable it, so the classic GPU finder runs either way. Measured anyway, both engines on the same frames across five datasets including very weak ones: 2400 frames, 638260 spots, not one difference - identical lists, identical indexing rate, identical merge statistics to every printed digit. On a large detector with eight workers the median per-image cost falls from 94 to 59 ms and preprocessing from 21 to 6 ms; throughput rises from about 48 to 55 Hz. No percentile regresses, which is what matters for a service - the ninetieth improves from 128 to 74 ms and the tail with it. Spot finding gets faster too, because the large copy no longer contends with the device gather. Correct two statements while here. The flag's comment and the data-analysis document both said the online receiver uses the CPU adaptive finder; online never runs an adaptive finder at all, and the copy the flag really controls was not mentioned. That copy would be better expressed as what it is - whether a host engine will read the image, which the constructor already knows - rather than inferred from which spot finder is wanted.

leonarski_fandClaude Opus 5	4bdb229fb8	spot_finding: find connected components on the GPU ... The spot finder flagged strong pixels on the device and then labelled them on the host, so every frame sent the packed bitmask back - 2.26 MB on a large detector - and the host walked all of it to recover a few hundred pixels. Do the labelling on the device instead: compact the bitmask into a flat-index-sorted list, find each pixel's backward neighbours by binary search, union them lock-free with path halving, then label, accumulate and filter in one kernel. Only the spot list comes back, and only one stream synchronisation per frame. The gain in the ordinary case is modest - about a quarter off per-image spot finding - because the host algorithm is genuinely fast on a normal frame. What justifies it is the frame that is not ordinary. The host labels a sorted sparse list through a window spanning two detector lines, so its cost is quadratic in how many strong pixels share a line. A lit band of detector rows - a hot module, a panel edge - costs 33 ms at two rows and 377 ms at fifteen, all of it under the pixel cap that was supposed to bound this, and none of it maskable when the cause is a diffraction ring rather than a defect: a ring runs tangent to a row at its top and bottom, which is exactly the shape that hurts. The device version is flat at 0.05 to 0.64 ms across every geometry tried, so an online run no longer stalls a quarter of a second on an ice ring. Rejecting an over-cap frame is now free too, since the count is known before any pixel is written. Also label once and filter three times. The per-image minimum-pixel search runs the extraction at three settings, but that setting only decides which components are kept - it does not change the components - so the search itself need not be repeated. This helps the host path as much as the device one. The resolution mask moves to the device as a bit mask, uploaded when the limits change rather than per frame, since the compaction needs it there. Parity is asserted permanently rather than argued: five cases covering realistic frames, occupancy from a hundred pixels to past the cap, the pathological geometries including rings, the resolution mask, and a hundred-repeat determinism check - requiring the same partition, the same spot order, and identical counts. The centroid is a float sum and therefore order-dependent, so the device walks each component from its root in ascending order and fuses its multiply-add the way the host's does; note that whether the host fuses at all depends on the architecture flags, so exact centroid equality is asserted where the compiler fuses and a two-ulp bound otherwise. Making those accumulators integer would remove that dependence entirely and is worth doing separately. Regression set: all 37 crystals identical to the last printed digit. Unit suite passes with the new cases. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-02 13:34:43 +02:00
leonarski_fandClaude Opus 5	1a1e05ad14	spot_finding: run the same two passes on the CPU as on the GPU ... ImageSpotFinderGPU::Detect launches its kernel twice, feeding the first pass's strong-pixel bitmap back in so the second recomputes each local background with those pixels excluded and keeps them strong. The CPU finder ran a single pass, so the two returned different spot lists for the same frame and a dataset processed without a GPU did not match one processed with it. It matters for any spot wide enough to reach into its own 31x31 background box: the spot inflates the mean and variance it is then tested against, so its outer pixels fail the SNR test. On the test image added here - a 5x5 core at 300 counts with a one-pixel ring at 25 - a single pass returns the 25-pixel core and 7500 counts where two passes return the full 49 pixels and 8100. pxl_val also becomes int64_t, matching the GPU's pixel_result signature. It was int32_t, so pxl_val * pxl_val overflowed above 46341 counts even though the surrounding sums were already 64-bit. The new parity test compares PixelCount and Count, not just the centroid, which does not move for a symmetric spot whether or not the ring was picked up; it was confirmed to fail against the old single-pass CPU.

leonarski_fandClaude Opus 5	b5b7cf2cf9	docs: say what the CPU prediction path actually does ... BraggPrediction.h claimed the buffer "GROWS to whatever a frame actually predicts, so a large cell is never truncated here". Only the two GPU Calc overrides call GrowCapacity; both CPU predictors stop at max_reflections. The cap is applied inside the h/k/l walk and before the resolution test, so what survives is the low-|h| block, not the reflections nearest the Ewald sphere - a cell large enough to overflow 20000 gives different merged reflections with and without a GPU. Documented rather than silently claimed otherwise. Also removed a paragraph describing a once-per-predictor overflow warning that no longer exists, and fixed the rugnux_cli.cpp path in HDF5.md.

leonarski_fandClaude Opus 5	66e705c0fe	docs: correct the FPGA analysis limits and the square-root coefficient ... The azimuthal bin limit is FPGA_INTEGRATION_BIN_COUNT = 2048, not 1024. There are 16 ROIs, not 64, and the map is a 16-bit per-pixel mask, so a pixel belongs to any subset of them rather than to exactly one. The lossy transform is round(sqrt(N*N*X)) = round(N*sqrt(X)): the HLS squares the sqrtmult register before multiplying. The doc said sqrt(N*X), which is off by sqrt(N), and the register comment claimed the value was "minus one" and "should be square of the coeff" - both wrong, the host writes N and the FPGA squares it.

leonarski_fandClaude Opus 5	0ca159449f	Bragg integration: integrate as far as the detector reaches, not to a fixed 1.0 A ... BraggIntegrationSettings::DMinLimit_A had a setter that nothing anywhere called, so it was always its 1.0 A default - in rugnux, the viewer and the broker alike, with no option or API field to change it. It feeds the predictor as high_res_A, which discards any reflection with |q| > 1/d_min, so integration simply stopped at 1.0 A however far the detector reached. Five of the 33 rotation test datasets have detectors reaching past it, down to 0.981 A. On one of them, run with no resolution limit, the shell table ended dead at 1.00 A with that shell still at CC1/2 55.6% and <I/sig> 3.4 - cut mid-shell rather than fading out. This branch had already made the sibling limits detector-driven (spot finding, scaling), so the pipeline was finding spots the detector could see and then refusing to integrate them. Make it a std::optional: unset means as far as the detector reaches, a value limits. The limit is only a bound on how far the lattice walk goes, never a second opinion on what is measurable - both predictors independently drop reflections that miss the detector (BraggPrediction.cpp, BraggPredictionRot.cpp) - which is what makes the detector's own reach the right default. rugnux gains --integration-high-resolution (0 = no limit, as for --spot-high-resolution); the derived per-axis prediction range resolves against the same number, so the two cannot drift. Full battery: 30/33 space groups, unchanged from before, 0 failures and the same three known mismatches; 22 of 32 crystals bit-identical and nothing worse than 5 observations in ~500k. The datasets that gain do so because their detector reached past 1.0 A - the effect is understated here because the harness caps each merge at the XDS resolution anyway.

leonarski_fandClaude Opus 5	b0e315e73c	Bragg prediction: derive the lattice walk from the cell, and expose it in the API ... Follow-up to making max_hkl a setting: it is now an optional, and unset means "take it from this crystal". The predictor keeps only |q| <= 1/d_min and h = a.q for the real-space axis a, so |h| <= a/d_min exactly - and likewise |k| <= b/d_min and |l| <= c/d_min. max(a,b,c)/d_min therefore bounds all three at once: nothing that could be predicted lies outside it, and nothing inside it is reached by a shorter axis. It applies to rotation and stills alike, both going through the one place the prediction settings are built. Offline (rugnux, viewer) the default is unset, so every crystal gets its own range; --max-hkl overrides it. Online the broker holds a concrete number, because the cost is the cube of it per image and a live acquisition should not have its frame rate decided by whichever sample is mounted: max_hkl joins bragg_integration_settings in the OpenAPI with a default of 100, so an omitted field arrives as that default (the generated model carries it) rather than as "derive it", and the frontend exposes it next to the integration model. Measured against a fixed 100 on six rotation crystals: three are bit-identical, two were being truncated and recover 419k and 5.8k observations with the high-shell CC1/2 going 15.1 -> 25.8% and 52.1 -> 55.3%, and the space group is unchanged 6/6. It reproduces a fixed 200 exactly, which is the bound being tight rather than merely safe. The sixth is worth recording: a 149/83/226 A cell derives 227, and because a single scalar has to cover the longest axis the cube is ~16x what a per-axis box would be - 22% wall clock, for a net 22 observations out of 364k (the per-frame 65536-reflection cap re-selects at the margin when more candidates are offered) and identical CC1/2, ISa and space group. Per-axis limits would remove that; the predictors already map a thread index to h, k and l separately. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 13:10:58 +02:00
leonarski_fandClaude Opus 5	a06c06931f	Bragg prediction: how far to walk the lattice is a setting, not a literal ... max_hkl was hardcoded to 100 at the one place production builds the prediction settings, so the only way to change it was to edit and rebuild - and it is not a constant of the method, it is a property of the cell. An axis is truncated once a/d_min exceeds it: 100 covers a 150 A axis at 1.5 A, but the same axis at 1.0 A, or a 250 A axis anywhere, loses its outermost reflections with nothing said. Move it into BraggIntegrationSettings next to the other prediction/integration parameters and add rugnux --max-hkl (1..511, default 100 - no behaviour change). Like the integration radii and the background trim it stays out of the OpenAPI, so the broker keeps the default it has today and live analysis cannot be handed a range that would not finish; the offline front end, which knows its cell, can ask for more. RugnuxCommandLine emits it when it is not the default. Measured on five rotation crystals at --max-hkl 200: two are bit-identical at no cost, and three were being truncated - one gains 419k observations (+17%) and takes its high-shell CC1/2 from 15.1% to 25.8% for +14% wall clock, the other two gain 12k and 5.8k observations with CC1/2 76.6->82.4% and 52.1->55.3% for +9% and +1%. ISa is unchanged throughout, and no frame overflowed the prediction buffer. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 12:00:45 +02:00
leonarski_fandClaude Opus 5	3e56d96921	Stills partiality: adopt the refined tilt only when it fits better ... RefineOne re-measured the image's correlation to the reference after writing the refined partialities - because --min-image-cc drops images by it - and then ignored what it measured. A crystal the tilt model suits worse than the fixed partiality it replaces kept the refined model anyway, and the refinement is on by default. Compare against the CC the crystal arrived with and put it back untouched when the refinement does not improve it, which is the same state a crystal with too few reflections to fit ends in. Also four things noted in review and left until now: AdaptiveThresholdTest.cpp was listed twice in the test target, AdaptiveThreshold.h was the one header in image_analysis/spot_finding not in its library's source list, CLAUDE.md said update_version.sh rewrites VERSION when it only reads it, and the CHANGELOG did not mention that image_scale_b is gone from the plot_type enum - which breaks a client that asks for that plot.

leonarski_fandClaude Opus 5	a3feb1271c	docs: CPU_DATA_ANALYSIS describes the algorithms, not their history ... The document had accumulated development narrative: what was tried and rejected, which datasets a change rescued or cost, measured percentages from test batteries. That belongs in commit messages and reports, not in a reference description of the pipeline - it dates quickly, and a reader looking up what an algorithm does has to sort it out from how it came to be. Removed throughout, keeping the algorithmic content and the design reasoning that explains a choice on principle: * 3.2 the whole paragraph justifying the rotation spot-finding limit from battery measurements, and the CPU-vs-GPU per-frame timings; * 3.3 "a significance/z-score was considered but is uninformative"; * 7.4 / 7.5 the comparisons to a robust loss and to joint refinement as approaches that had failed; * 9.2 the R_meas / CC1/2 outcomes attributed to the trimmed-mean background; * 9.3 "per-detector-region and crystal-anisotropy profiles were evaluated and add nothing"; * 10.2 the stills tilt "succeeds where a freely-fitted width collapses"; * 10.5 the CC_anom argument, trimmed to why the statistic behaves as it does; * 10.6 the survey of per-frame correlation medians across datasets; * 13 the space-group bullet, restructured into the three gates it actually applies, dropping the dataset anecdotes; * 14.2 the free-form per-shell rescale, stated as a design choice rather than an experiment. Section 13's space-group text was one 20-line paragraph; it is now a numbered list of the three tests, which is what the code does.

leonarski_fandClaude Opus 5	0f1851cf82	rugnux: drop the 1.5 A spot-finding limit on rotation data ... Rotation kept a 1.5 A high-resolution limit for spot finding on the strength of one indexing-rate measurement (100.0 -> 96.8% on a strong set). Measured properly, over the whole 33-crystal rotation battery, it does not earn its place: * no space-group decision changes - the same 30/33 agree with XDS, and the three that differ are the known pre-existing cases, unchanged; * 29 of 33 crystals are identical to the digit - same indexing rate, R_meas, CC1/2, ISa. The limit was doing nothing on the large majority; * where it does bite, the limit is the worse setting. The one crystal that loses appreciable indexing rate without it (99.50 -> 94.22%) comes back with lower R_meas (29.4 -> 28.1), higher high-resolution CC1/2 (27.9 -> 29.1) and higher ISa (5.77 -> 6.17). Another loses 0.4% of frames and gains 2.8 points of CC1/2_hi. Fewer frames indexed, better data from them; * runtime is unchanged (16m46s vs 17m32s over the battery). So the indexing-rate cost is real but does not carry through to the merged data, which is what the limit was protecting. Unset now means "as far as the detector reaches" for rotation as well as stills; --spot-high-resolution still sets a limit for weak, high-background data where the extra high-resolution spots are genuinely noise. This also removes the flag that distinguished "the user asked for no limit" from "the user said nothing" - with no rotation default left, both mean the same thing. While rewriting the comment block, corrects its neighbouring claim that rotation keeps the fixed-threshold finder; adaptive detection has been the default for both workflows since 6f4917dce.

leonarski_fandClaude Opus 5	323c76abde	docs: correct CPU_DATA_ANALYSIS against the code it describes ... Ten places where the document and the implementation had drifted apart. Each was checked against the source before rewriting: * 7.5 rotation post-refinement: it is TWO separate cross-validated steps (cell+axis from the angles, then distance+beam from the positions with the cell fixed), not one joint fit against the merged fulls; the held-out split is an hkl hash, not a frame split; the bounds are +-5% on distance and +-15 px on the beam, not "under ~1%"; and only the distance and beam centre reach pass 2, which re-indexes de novo. * 9.2 the trimmed-mean background: it is computed in the shared background pass, so it DOES apply to --integrator boxsum. Only the broadband sigma-clip is excluded. The section previously said both, contradicting itself two paragraphs apart. * 9.3 per-reflection profile rebuild, sub-pixel centring and radial elongation are gaussian-only; the empirical profile keeps the fixed per-shell grid and is accumulated on rounded predicted positions, not centroids. * 10.5 the asymptotic ISa and the b_ISa sigma floor are rotation-only; stills report 1/b and floor with the whole-range b. * 8.4 centering absences are applied only when the user fixes the space group - de novo, prediction runs in P so the search can confirm the centering from the intensities. * 10.6 per-batch relative-B cross-validates on ASU-group parity, not the frame parity the other surfaces use. * 13 the resolution cutoff sits one reported-shell width PAST the CC1/2 = 0.30 crossing, so data below 0.30 are kept. * 7.1 the orientation-only prior penalises all three components of the angle-axis vector. * 10.1 rlp is the RECIPROCAL Lorentz factor, L = 1/rlp. * 14.3 the model scaling is fitted over work and free reflections alike, so R-free is free of refinement, not of the scaling fit.

leonarski_fandClaude Opus 5	40acf1ffc4	rugnux: search the space group twice by default on rotation data ... --search-min-zeta now defaults to 0.85 for rotation, so the de-novo search runs on a merge of all the observations AND on a merge of only the well-measured ones, and keeps whichever found more symmetry. Previously it shipped off and the second opinion had to be asked for. Rotation battery, 33 crystals, NO flags beyond the resolution limit: fixed-threshold finder 30/33 - zero crystals differ from the single search adaptive finder 30/33 - the same three mismatches Both arms now agree crystal for crystal, which they have not done before. The last disagreement was a thaumatin set whose 4-fold sits 88.9 deg from the spindle: at defaults it now reads P42(1)2 (all-observation merge -> 222, Lorentz-filtered -> 422, higher taken) where it read P222. The classic arm is a strict no-op - zero differences against both the explicitly-flagged run and the run predating the dual search - so the default costs nothing where the geometry is not the problem, and 47.2 s against 47.8 s on the same crystal back to back. The default is safe to set because the two searches can only disagree by a LOST operator: discarding observations starves an operator correlation, it cannot invent one. That also makes the 0.85 itself uncritical - too aggressive a cut only means the second opinion contributes nothing and the full merge wins. --search-min-zeta 0 restores the single search. Docs: CHANGELOG gains a 1.0.0-rc.161 section covering the branch, and CPU_DATA_ANALYSIS records the four analysis changes of this work - the confidence-weighted per-image refinement, the collapsed per-frame scale guard, the opt-in per-image rejection, and the operator-disagreement criterion with the two-search rule.

leonarski_fandClaude Opus 5	6f4917dcee	rugnux: adaptive spot detection is the default for rotation data too ... It was held back because a 33-crystal rotation battery showed it breaking three crystals deterministically - a lost space group, a halved indexing rate and a collapsed merge. None of those causes turned out to be in detection. The extra spots adaptive finds are real. Measured per spot against a finder-neutral local background: 64% recur at the same position on the adjacent frame (chance rate 0.5%) with 2-frame rocking curves, and 0.00% would fail a conventional local SNR >= 4 test, median local SNR 34. What they include is genuine peaks belonging to no lattice the indexer found, and the damage they did scaled with their absolute COUNT (80.6 per frame against 36.8 for the fixed finder), not with their quality - which is why nothing aimed at judging individual spots ever worked. The three failures fell to fixes elsewhere: merge collapsed - a per-frame scale free to collapse toward zero amplified two junk frames by 546x (704098712, ec7a82613). Not a detection problem at all: the fixed-threshold finder trips the same bug on a different frame range. space group lost - the per-image geometry refinement was dragged 2.3-2.8 deg off by the weak-spot tail in an unweighted fit; weighting each spot by how strong it is FOR ITS RESOLUTION fixed it (ae126c3d5), and gained a point group for the fixed finder too. indexing halved - gone with the same two; that crystal is now better under adaptive (CC1/2 92.6 -> 95.9, high-shell 44.9 -> 56.4). Battery, 33 crystals, adaptive vs the fixed finder: exact space group matching XDS 26/33 vs 25/33 point group matching XDS 29/33 vs 30/33 ISa better on 6 crystals recovers a screw axis the other misses (P321 -> P3121) The one point group it loses is a tetragonal crystal where adaptive collects 2.4x the observations at better R_meas (21.4% vs 28.3%) and better ISa (4.58 vs 2.91), and forced to the right group gives CC1/2 99.2% at multiplicity 10.7 - matching XDS. Only the automatic symmetry call fails there, and six candidate causes have been measured and refuted (mixed indexing hands, off-crystal frames, a badly integrated minority, radiation damage, pseudo-tetragonality, uncorrected anisotropy). It is left as the subgroup, which is the recoverable direction: -S gives XDS-quality data from the same run, whereas the failures this unblocks were not recoverable. --no-adaptive-spots reverts to the fixed-threshold finder.

leonarski_fandClaude Opus 5	16bf3408f0	Address code-review findings; make detection limits detector-driven ... One changeset, developed together in response to a review of this branch, so the files carry several of the changes at once. Full test suite passes (733 cases). Spot finding - Split ImageSpotFinder into Detect() (flag strong pixels - the expensive per-pixel pass) and ExtractSpots() (CCL + min/max-pix + resolution mask), with Run() = both. The per-image min-pix escalation now detects ONCE and repeats only the cheap extraction, instead of re-running the whole finder four times per frame as it did on the default path. It also keeps the winning attempt's spot list rather than re-extracting it, so the frame that is integrated is exactly the frame that was scored - which a GPU re-extract could not guarantee (float atomic ordering). - spot_finding_time_s no longer swallows indexing time, and indexing_time_s now sums every escalation call instead of reporting only the last. Detection limits follow the detector - The azimuthal-integration upper q and the spot-finding high-resolution limit are now std::optional, in the C++ structs AND in the OpenAPI schema, and resolve to the detector's own maximum (DiffractionExperiment::GetDetectorMaxQ_ recipA). Adaptive detection reads a pixel's ring from the azimuthal bins, so a pixel outside that q range could never be strong - the integration range silently bounded what detection could see, regardless of the requested resolution limit. Regenerated the C++ and TypeScript clients; the viewer and the web frontend each gained a "to detector edge" switch. Detection defaults are now per workflow (measured, not assumed) - Stills: adaptive detection, min-pix chosen per image, no resolution clipping. - Rotation: fixed-threshold finder, min-pix 2, 1.5 A limit. On a 33-crystal rotation battery, adaptive detection helped four hard crystals but deterministically broke three (a lost space group, a halved indexing rate, a collapsed merge), and the detector-edge limit cost indexing on a strong rotation set (100.0 -> 96.8%). Each is still overridable by its flag, and --no-adaptive-spots is new. Indexer seed escalation - Stop escalating once a seed's lattice explains >= 90% of the seed spots. Previously any frame with >= 80 spots always paid three indexer calls, online broker included. Merge-consistency filter - --min-image-cc gated on a per-image CC computed BEFORE the stills partiality post-refinement and never refreshed; the refiner now recomputes it, so the reported CC describes the data that are actually merged. - Replaced the per-call cc_mask argument with one MergeOnTheFly flag, so the merge, the error model and MergeStats can no longer disagree about which images are in (the --scale path merged unfiltered while its statistics were filtered). Per-image B-factor refinement (-B) removed - Measured on four serial-stills datasets: it is a no-op where the per-image fit is well conditioned and actively harmful where it is not (CC1/2 -8.1, R_meas +23.2 on the weakest large-cell set, whose fits hit their [-50, 200] bounds on 14-25% of images). It had also been silently DISCARDED since the partiality post-refinement landed - reported but not applied. Rather than fix and keep a knob with no demonstrated benefit, the flag and the whole image_scale_b_factor chain are gone: setting, scaling fit, message field, CBOR, HDF5 write and read-back, per-image plot, OpenAPI enum, viewer column and checkbox, docs. ScaleOnTheFly no longer needs Ceres at all - the fit is a linear IRLS. (The Wilson per-image b_factor is a different quantity and stays.) Stills partiality width now fits both of its components - sigma^2 = gamma0^2 + (gamma_e*d*)^2 instead of a purely angular gamma_e*d* with gamma0 pinned to 0. Fitted per crystal by least squares of dist_ewald^2 on d*^2. The angular-only width is fitted over a d*^2-dense population, so it was pinned by the high-resolution edge and collapsed at low d*: median partiality 0.008 beyond 13 A for reflections that were plainly recorded, 55% of them under the merge's partiality floor, and the survivors divided by those values - which inflated the merged low-resolution intensity scale 3.6x (~ +9 A^2 of apparent B). Measured on 5000 stills: the ramp flattens to 0.89x, no observation is dropped any more (701750 -> 716811), shell-mean CC1/2 and R-free improve slightly. Note CC1/2, R_meas, completeness and a B-refining R-free are all blind to that ramp, which is why it survived earlier validation; the cost is high-resolution R_meas (98.5 -> 101.9 shell-averaged). Removed dead code from add-then-remove churn - Prediction-time "still partiality" (unreachable: no setter), the phantom IndexingSettings::min_indexed_spot_fraction knob (getter, no setter - now the constant it always was), StillsPartialityRefine's caller-less Settings constructor and its reference to a long-gone env var, ProcessImage's unread bool return, an unused include, and a dead viewer overlay hook. Also - Viewer: the magnifier compared a QImage with itself, so its scene rect was set once ever and it could not pan into a larger dataset; the hover tail timer could fire after leaveEvent and resurrect the resolution readout outside the image. - update_version.sh regenerated the frontend lock file BEFORE bumping the version (every release shipped an off-by-one lock), and did git rm/git add on a path that has not existed since the client moved to src/client - with no set -e, both failed silently. - fpga/pcie_driver/postinstall.sh tested "[ ! occurrences > 0 ]", which is a redirect, not a test, so dkms add never ran. - Unit tests for the adaptive-threshold host functions, which had none.

leonarski_fandClaude Opus 4.8	a8c1006c49	Choose min-pix-per-spot adaptively per image for serial-stills indexing ... For stills indexing the minimum-pixels-per-spot filter is now chosen per image instead of being fixed: the frame is indexed at min-pix 3/2/1 and the setting that maximises indexed-spot count weighted by indexed fraction (n_indexed^2 / n_total) is kept, then integrated once at that min-pix. The fraction factor keeps a smaller min-pix's extra spots only when the lattice actually explains them, so strong frames retain their real weak spots (extending resolution) while noise-flooded frames stay strict. The mode is selected by the presence of --min-pix-per-spot, now optional (SpotFindingSettings::min_pix_per_spot is std::optional<int64_t>): omit it for the adaptive per-image path, give a value to force a fixed min-pix. It applies only to the stills indexing path -- rotation indexing builds one global lattice and keeps a fixed min-pix, and the online receiver and the FPGA host path always carry a concrete value, so neither changes. IndexAndRefine::ProcessImage now returns whether the frame indexed, to drive the per-image selection. Exposed in the jfjoch_viewer spot-finding settings (adaptive-threshold and adaptive-min-pix checkboxes, each greying out the control it overrides); the broker uses neither. Validated on the full rotation regression battery (no regression) and the whole serial-stills target battery at full image count.

leonarski_fandClaude Opus 4.8	9fdeed282a	Add fused GPU adaptive spot finder (azint + spot finding in one pass) ... AdaptiveSpotFinderGPU does the per-resolution-ring reduction once on the GPU and drives both products from it: the azimuthal-integration profile (corrected space) and the self-calibrating adaptive spot-detection threshold (raw counts). This replaces the separate GPU azint pass and the host-side adaptive spot finder that runs on the GPU path today. On a ~4.5 MP detector it does both jobs in ~1 ms/frame versus ~40 ms for the CPU adaptive finder (~42x), with an identical spot list and azimuthal profile. The per-ring threshold math (Poisson tail + read-floored Gaussian, operating point from the false-pixels-per-frame knob) is factored into AdaptiveThreshold.h so the CPU and GPU finders share one source of truth and cannot drift. Wired opt-in via a MXAnalysisWithoutFPGA constructor flag, default on for the rugnux offline path and the interactive viewer, off for the online receiver (so the broker path is unchanged). When on, Analyze() skips the separate azint pass and lifts the profile from the fused engine. The viewer gains an "Adaptive threshold" checkbox that greys out the signal/noise and photon-count sliders (the adaptive finder uses neither). Dedicated tests exercise both products (spot-finding parity vs the CPU finder, azimuthal profile vs a standalone GPU azint) plus a speed benchmark. Validated end-to-end on lysozyme serial stills: fused == CPU-adaptive index rate and merge stats. Docs: new section 3.2 in docs/CPU_DATA_ANALYSIS.md.

leonarski_f	67dca388bd	v1.0.0-rc.160 (#70) ... This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use. * rugnux: Add `--model model.pdb` - score the merged data against an atomic model and compute initial maps. It reports R-work/R-free (scaling the model to the observed amplitudes with an overall scale, an anisotropic B and a flat bulk solvent - the standard few-parameter model, so a batch of maps stays directly comparable) and writes 2Fo-Fc / Fo-Fc electron-density maps (CCP4) plus a map-coefficient MTZ. The structure itself is not refined; the model is only re-fractionalised into the data cell. * rugnux: The merged reflection output now carries French-Wilson amplitudes (|F| and its sigma) next to the intensities - MTZ `F`/`SIGF`, mmCIF `_refln.F_meas_au`, and the text HKL - computed with the correct centric/acentric Wilson prior and epsilon multiplicity, so a downstream program (e.g. phenix.refine) can refine against amplitudes. The intensity columns are unchanged. * rugnux: R-free test-set flags are now assigned deterministically and consistently across symmetry - a Bijvoet pair I(+)/I(-) is never split between the work and free sets, and the assignment is a reproducible per-hkl hash that depends only on the reflection index, so every dataset of one crystal form gets the same ~5% free set (what a multi-dataset campaign such as PanDDA needs). On small data the fraction is floored so the test set stays large enough for a stable R-free (~500 reflections, capped at 10%); it stays flat at 5% on ordinary data. When a reference MTZ carries a `FreeR_flag` column its test set is imported instead, letting a whole campaign inherit one shared free set. * rugnux: A reference MTZ (`--reference-mtz`) can now fix the space group and cell for rotation data too (previously rejected), without being used to scale - the rotation merge stays self-consistent. When the crystal has an indexing (merohedral) ambiguity - a lattice symmetry higher than its Laue symmetry, e.g. P3/P4/P6/C2 - the reference also resolves it: each candidate reindexing (identity plus the twin-law cosets of the metric symmetry) is scored by its intensity correlation against the reference and the data are re-merged in the best-correlating one. This is a metric-preserving relabelling of hkl (the cell is unchanged) and a no-op for a holohedral crystal such as lysozyme. * rugnux: `--model` validation now aligns the data to the model before scoring - the observed reflections are reindexed into the model's enantiomorph when the two differ only by hand (indistinguishable from merged intensities). A merohedral indexing ambiguity is resolved against the reference MTZ when one is given (so a whole campaign shares one indexing convention); only with a model and no reference does validation fall back to fitting each candidate reindexing and keeping the lowest R-free. * rugnux: De-novo symmetry - recover a genuine high-symmetry group whose data are imperfectly scaled. Such a merge's within-orbit chi² lands just past the self-consistency bound (each real symmetry step adds a little systematic scatter), right where a merohedral twin also lands, so the chi² ratio alone cannot separate them. The candidate is now rescued when the extra intensity-proportional systematic error it invokes stays small relative to the confirmed subgroup - a genuine symmetry step gains multiplicity without inflating the merge error model's b, whereas a twin forces non-equivalent reflections together and b balloons. Fixes cubic insulin (I23 instead of I222) with no change to any other crystal in the test battery, including the twins that must stay in their lower symmetry. * Docs: Document the French-Wilson amplitude estimation, R-free flagging, reference-based space-group/ambiguity resolution, and model-based validation/maps in CPU_DATA_ANALYSIS.md. * Frontend: The status-bar pill now shows a progress bar during detector calibration (previously only during measurement), and the calibration state and its button are labelled "Calibration"/"CALIBRATE" (the internal `Pedestal` state name is unchanged for back-compatibility).Reviewed-on: #70 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch>	2026-07-19 09:39:28 +02:00

leonarski_f	451310f43d	v1.0.0-rc.158 (#68) ... This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use. * Analysis: The azimuthal-integration solid-angle correction now follows the incidence angle to the detector normal (`cos^3` of that angle) instead of `cos^3(2*theta)`, so it is correct for a tilted detector and matches PyFAI `solidAngleArray` and MAX IV azint (unchanged for an untilted detector). Crystal geometry refinement (`XtalOptimizer`) no longer silently ignores an imported PONI `rot3` (rotation about the beam): it is applied as a fixed rotation in the residual so refinement stays consistent with the rest of the pipeline. Polarization and azimuthal binning already honoured `rot3` through the full PONI rotation. * jfjoch_viewer: Open datasets on the WSL2/UNC filesystem (paths starting `\\`); write processing outputs next to the input file, with a Browse button and independent `_process.h5` / merged `.mtz`/`.cif` toggles; and show the determined space group in the merge-statistics window. * rugnux: Accept an absolute `-o` output prefix in offline processing. * Packaging: The self-contained Linux viewer `.tgz` now bundles cuFFT, so it runs without a system CUDA toolkit (`.deb`/`.rpm` are unchanged, distro-managed). * Docs: Bring the analysis references up to date with the code. `docs/CPU_DATA_ANALYSIS.md` now reflects the unified profile-fit Bragg integration engine, multi-lattice indexing, azimuthal phi binning, the radial parallax/bandwidth profile with sub-pixel centring, the rot3d capture-fraction handling and the automatic CC1/2 resolution cutoff, and drops the descriptions of features that were never implemented (French-Wilson amplitudes, the still excitation-error partiality model); `docs/RUGNUX.md` documents the new `--resolution-cutoff`/`--resolution-cc-target`/`--resolution-shells`, `--min-captured-fraction`, `--mosaicity`, `--reference-column`, the azimuthal correction toggles and the geometry-override options, and corrects the `-N` default. The outdated in-source design notes (ICE_RING_DETECTION, BRAGG_INTEGRATION_ENGINE, NEXTGEN_INTEGRATOR) are removed.Reviewed-on: #68 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch>	2026-07-12 19:42:29 +02:00
leonarski_f	54c0100e8e	v1.0.0-rc.157 (#67) ... This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use. * rugnux: Rebrand the offline data-processing subsystem as `rugnux` and consolidate all offline analysis into the single `rugnux` binary - `jfjoch_process` is now `rugnux`, the former `jfjoch_azint` is now `rugnux --azint-only`, and `jfjoch_scale` is now `rugnux --scale` (see the new docs/NAMING.md and docs/RUGNUX.md). Scaling and merging are on by default for rotation and stills (`--no-merge` disables them), replacing the previous opt-in `-M, --scale-merge`. * rugnux: CLI fixes - default `-N` to all hardware threads, parse numeric option arguments strictly (reject non-numeric or trailing input instead of silently yielding 0), require `--wavelength > 0`, and correct the reproduced command line and `--scale` reference-cell handling. * rugnux: De-novo space-group improvements - recover genuine high symmetry and centred Bravais lattices from intensities, add an automatic CC1/2 high-resolution cutoff, and report L-test twinning statistics. * rugnux: Index weakly-diffracting low-resolution rotation data that previously failed (e.g. F-cubic crystals that diffract only to ~4 A on a detector reaching ~1.5 A). The per-frame indexing gate now measures the indexed fraction only within the resolution range the lattice actually diffracts to, so the many sub-diffraction ice/noise spots no longer make the fraction floor unreachable; the two-pass first pass tries several image-sampling schemes (spread across the whole rotation vs a consecutive wedge whose native stride keeps a reflection's rocking curve continuous, letting the FFT resolve a long axis) and keeps the one that indexes the most frames; and the de-novo space-group search no longer discards all reflections (and crashes) when every resolution shell falls below <I/sigma> = 1. * rugnux: Lower the low-resolution R-meas for strongly-diffracting rotation data - drop edge-of-sweep truncated fulls whose rocking curve was captured below `--min-captured-fraction` (default 0.7 for rotation), and report R-meas only over the observations kept by outlier rejection (matching XDS). The 0.7 default also strips the partiality-extrapolated fulls that dominate the intensity second moment on weakly-diffracting crystals, so the de-novo space-group search is no longer starved by the error-model I/sigma floor and recovers the correct symmetry (e.g. the F-cubic Benas crystals: Benas_3 -> F432, Benas_7 -> P6122, instead of P4/P1); on the reference battery every other crystal keeps its space group. * rugnux: Write the refined geometry (beam, tilt, axis) to _process.h5 and place non-standard mmCIF items under a reserved `jfjoch` prefix. * jfjoch_broker: Ordinary acquisition failures (receiver/writer/analysis problems, missed packets, writer disconnect) now return to the Idle state with an Error-severity message, so a run can be retried without an expensive re-initialisation; only failures that leave the detector in an undefined state (new JFJochCriticalException, e.g. PCIe/FPGA faults) go to the Error state and force re-initialisation. * jfjoch_broker: A synchronous /start now reports its failure to the HTTP caller instead of returning HTTP 200, and an incomplete or truncated dataset (missing packets, writer disconnect) is reported as an error rather than a "reduce frame rate" warning. * jfjoch_broker: Drop uncollected placeholder rows (number = -1) from the scan_result REST endpoint. * jfjoch_broker: Fix the inverted per-image compression ratio reported by the Lite receiver (was compressed/uncompressed instead of uncompressed/compressed). * jfjoch_broker: Bragg integration adds a quantization-noise variance floor with a box-sum fallback, and treats the type-maximum marker as an invalid pixel for unsigned image types. * jfjoch_writer: Detect file-overwrite conflicts at start for back-channel transports, and reset the writer when end-of-collection finalisation fails. * jfjoch_viewer: Preview overlays follow the geometry (resolution/ROI arcs, true beam centre, predictions, coral secondary-lattice spots, legend), add save-as-JPEG, and fix an HTTP live-follow memory leak. * Frontend: Improved aesthetics and usability, and added in-browser pixel-mask and JUNGFRAU-pedestal visualisation. * CI: Name the Windows installer jfjoch-viewer-* instead of jfjoch-*.Reviewed-on: #67 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch>	2026-07-11 07:19:11 +02:00
