leonarski_fandClaude Opus 4.8	545ebdf868	Merge: per-crystal CC1/2-delta rejection (--reject-delta-cchalf) ... CrystFEL deltaCChalf-style per-crystal quality filter for heterogeneous serial data. Each image is assigned to one CC1/2 half, so removing it perturbs only that half's per-reflection means; deltaCChalf_i = CC1/2(all) - CC1/2(without image i). A negative value means dropping the image RAISES CC1/2 (it disagrees with the consensus). Images whose deltaCChalf is a low-side statistical outlier (< mean - N*stddev) are skipped when merging. Reference-free. Two passes over the retained integration outcomes; per-image contributions are re-derived rather than stored, so memory stays O(unique reflections + images) for full 200k-frame runs. New CLI flag --reject-delta-cchalf <N> (default: off). Validation (jet FFBIDX +C+S, sigma4): removing 17/4000 (3 sigma) raises CC1/2 95.1->96.1%, CCref 54.9->55.2; 2 sigma -> 96.1/55.3. Dataset-appropriate: it HELPS heterogeneous serial data (some crystals genuinely bad) but slightly trims a homogeneous single rotation crystal (c2 94.6->93.8 - no bad crystals, the relative cut still removes the tail), so it is opt-in. R-free is the real test (user's full 200k). Note: the reported overall N_obs still counts all observations; the exported merge (and CC1/2) correctly exclude the rejected images.

leonarski_fandClaude Opus 4.8	6f733d74c2	Merge: make outlier rejection a ScalingSettings parameter + CLI flag, default 6 ... Promote the per-observation merge outlier rejection from the temporary PR_REJECT env knob to a real setting: ScalingSettings::OutlierRejectNsigma (default 6, <=0 disables), driven into MergeOnTheFly via the constructor, with a --reject-outliers CLI flag in jfjoch_process. Default-on at 6 sigma matches XDS (MISFITS/REJECT) and DIALS (normalised-deviation test); it validated on the full-jet R-free (0.2625 -> 0.2585). Applies to both the PixelRefine and classical merge paths. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-15 12:42:25 +02:00
leonarski_fandClaude Opus 4.8	a47b376dc3	Merge: per-observation outlier rejection (env-gated PR_REJECT) ... At the jet's ~1000x multiplicity R-free is bias-limited, and the merge had NO outlier rejection - serial data zingers/overlaps/mis-indexed frames bias every merged mean. Add a robust per-observation cut: drop observations whose corrected intensity lies > reject_nsigma error-model sigmas from the reflection's MEDIAN. The error-model sigma already captures the genuine (partiality) scatter, and the median is a robust centre, so only the tail beyond the real spread is removed - not good partials. The median is computed in RefineErrorModel (which already pools the observations per reflection); AddImage applies the cut. Env-gated via PR_REJECT=<nsigma> (off by default); logs the count removed. On the jet (CC proxy) it lifts CCref +8 (nsigma 6, 0.6% cut) to +11 (nsigma 3, 7.4% cut) - the cut is vs the data's own median, not the reference, so the gain is real cleaner means. R-free validation + the nsigma sweet spot (over-rejection risk at low nsigma) are for Filip's full-jet R-free. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-14 20:56:53 +02:00
leonarski_fandClaude Opus 4.8	c93d381dc8	Error model: harden the fit against pathological inputs (code review) ... Addresses code-review findings on RefineErrorModel: - Floor the 1/dev^2 bin weight relative to the data scale (1e-3 of the median bin dev^2), not an absolute 1e-30: a near-zero-scatter bin could otherwise acquire a runaway weight and hijack the global (a,b) fit. - Reject a near-collinear normal-equation system relatively (det > 1e-10*Ass*AII) instead of with an absolute threshold that an ill-conditioned fit can pass. - Reset the model to identity at entry so any early return leaves it inactive rather than keeping a stale a/b alongside a freshly-cleared mean map (which would make CorrectedSigma fall back to the per-observation I). - PixelRefine: correct the orient_prior comment - with the sweep on, the LSQ anchor is the swept orientation (intended), not the spot-centroid one. Verified unchanged on the lyso test set (ISa 1.1, CC1/2 90.3%). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-12 18:53:02 +02:00
leonarski_fandClaude Opus 4.8	e6a50b45c7	Integration: mean background + global error model (trustworthy sigmas) ... Background estimate: use the mean of the local ring, not the median. For a right-skewed (Poisson) background the median sits below the mean, so subtracting it under-subtracts and biases every weak intensity positive; over multiplicity this becomes fake <I/sig> of a few in no-signal high-resolution shells. Fixed in both PixelRefine and BraggIntegrate2D (the classical route had the same bug). <I/sig> now tracks CC honestly and the true resolution limit is visible. Error model: fit a global a, b (XDS form sigma'^2 = a*sigma^2 + (b*I)^2) from the scatter of symmetry equivalents at the merge level (so both integrators benefit), and print it with ISa = 1/b in jfjoch_process. The (b*I)^2 term uses the reflection mean (not the per-observation I_i, which biases the weights and collapses CC); a,b come from a relative-weighted bin regression. Replaces the earlier per-resolution-shell variant, which was partly masking the background bias. METHODS.md: document both (Sections 6-7), integrator-agnostic.

leonarski_f	fc68a9baed	v1.0.0-rc.146 (#56) ... This is an UNSTABLE release. The release has significant modifications for data processing - in case of troubles go back to 1.0.0-rc.144. jfjoch_process: Generate a dedicated file (_process.h5), which can be used as a replacement for the _master.h5 file for a reanalyzed dataset. jfjoch_process: Improve the performance of scaling and merging, implement on the fly scaling. jfjoch_writer: All final data analysis results are repopulated in the _master.h5 file. jfjoch_scale: Dedicated tool for rescaling/merging existing data. jfjoch_viewer: Fix bugs where pixel labels where displayed on a wrong pixel. WARNING! Scaling and merging are experimental at the moment, and may not provide reasonable results for the time being. Reviewed-on: #56	2026-05-28 18:48:35 +02:00
