We are happy to hear from you if you manage to derive more insights from our datasets. * Datasets Datasets were collected over four sessions in 2020, 2021, 2022 and 2024.

Please examine the processed stream files (below) to see which runs were excluded. In addition, we deposited other datasets that were collected during the beam time for reproducibility checks but were not mentioned in the paper. Note that these images might not be suitable for biological/chemical interpretation (e.g. due to light contamination, laser being too weak or too strong). We nonetheless deposited them as they might be useful for e.g. data processing studies. * Geometry MPCCD contains eight panels (512 x 1024 pixels each). In the HDF5 files the eight panels are stacked vertically to give a 512 x 8192 pixel image for a frame. The optimised detector geometry is provided in the CrystFEL geometry format. Each beam time needs a different geometry file. * Processed stream file We have deposited processed CrystFEL stream files in the `Streams` directory. * Image processing Image files were written by Cheetah adapted for SACLA. Details of this pipeline have been published in https://doi.org/10.1107/S1600576716005720. The images are ready for processing by CrystFEL. A dxtbx module necessary for processing with DIALS is also available. See https://github.com/biochem-fan/cheetah/wiki for detailed explanations and tutorials. Data processing parameters we used are available in the header section of the stream files. Best parameters for newer versions of CrystFEL might be different. * Contact Questions about data processing should be addressed to Takanori Nakane. Other questions should be sent to Takafumi Ueno. Mail addresses are shown in the CXIDB.
