# README file for CXIDB ID 204 This deposition contains diffraction and dark images collected at SACLA for the following paper: Nakano et al., Three-dimensional structure determination of gold nanotriangles in solution using X-ray free-electron laser single-particle analysis, Optica 9(7), 776 (2022). DOI: doi.org/10.1364/OPTICA.457352 # Data files The deposition consists of 4859 diffraction patterns mentioned in the paper. They divide into 199 hdf5 files with run numbers. Dark images corresponding to each run number are also uploaded. #Geometry MPCCD octal detector data, which were used for data processing in the paper, are stored in the hdf5 files with an array of 2399 x 2399 pixels. #Source code The analysis codes for processing the diffraction data are available on the RIKEN box (https://riken-share.ent.box.com/s/eobvldhkul31rv965bvzhvofs3yuaca2).
