External test data: serial crystallography (XFEL stills)

The serial datasets of the still battery (tools/battery/still_battery.py, manifest tools/battery/still_manifest.json). Like the rotation sets on External test data, they were collected by other people, on detectors and in file formats we do not produce ourselves, and published for exactly this kind of reuse. All of them come from the Coherent X-ray Imaging Data Bank (CXIDB).

None of these data were collected by us. If you use any of them, cite the dataset DOI below and the paper of the entry.

Where the values come from

• Dataset DOI: the CXIDB entry's own DOI, resolved against DataCite before it was written down.
• Space group, cell, resolution and R-free are the values deposited with the PDB entry, read from the RCSB data API. Every entry is a dark or ground state refined against observed data.
• Images used are the frames in the files we use, counted in the files themselves. Where that is only part of the entry, the table says so and gives what the entry or the deposition holds.

The files we use

Paths are relative to the still data root of the site config (tools/battery/README.md). CXIDB serves https://cxidb.org/data/<entry>/...; most of it accepts HTTP range requests, so a broken download resumes with curl -C -.

The masks of the SwissFEL geometry files. rugnux takes the pixel masks and bad regions a CrystFEL geometry file names. The SwissFEL files name their mask with an absolute path on the facility's disk, so each set reads a copy whose mask_file is relative to the copy's own directory (a relative mask file is looked for in the working directory first, as CrystFEL does, then beside the geometry file): swissfel_103/ref/jf-16M_mask.geom is jf-16M.geom with mask_file = run47.JF06T32V01.mask.h5, and swissfel_213/ref/mbco_march_mask.geom is mbco_march.geom with mask_file = ../raw/march_dark_MbCO_II-March-06/data/pixel_mask/run_000243.JF06T08V01.mask.h5. Only that line differs.

The _int16 sets. The SwissFEL files store converted JUNGFRAU data as uncompressed float32 keV, 68 MB (JF16M) or 17 MB (JF4M) a frame, which caps reading at about 74 or 295 frames/s at 5 GB/s. The _int16 sets are copies with the same layout in which /data/data holds whole photons (keV divided by the photon energy, rounded) as int16 with bitshuffle/LZ4, about 25 times smaller; rugnux reads them with --gain 1 and merges them to the same numbers. Make them with tools/battery/still/float32_to_int16.py <in.h5> <out.h5> <photon energy keV> (h5py and hdf5plugin), into swissfel_103/conv/ (4.57 keV) and swissfel_213/conv/ (12.037 keV, keeping the tarball's directory tree), named <input>_int16.h5. One MbCO dark run (run_000238) holds no frames and has no copy.
