Two journals, Scientific Data and the Journal of Applied Crystallography, published special collections of papers on Aug. 1 that focus on X-ray free-electron laser (XFEL) research.  

The articles in both collections are a mix of new publications and papers originally published earlier in 2016.
The special collection in Scientific Data, titled “Structural biology applications of X-ray lasers” contains a commentary and six papers that examine data generated at the Linac Coherent Light Source (LCLS). The experiments describe structural studies of nanocrystals, single virus particles, living cells and cell organelles.
All experimental datasets in the series are openly available to the scientific community at the Coherent X-ray Imaging Data Bank (CXIDB). In their commentary, the organizers of the series, professors Janos Hajdu and Filipe Maia of Uppsala University, write that the data currently available is ​​just part of the “trickle before the torrent” of diffraction data that will eventually be produced by X-ray lasers.  

The Journal of Applied Crystallography published a related collection of papers about software for free-electron laser experiments in a special virtual issue titled “CCP-FEL: a collection of computer programs for FEL research.”

The introductory article and 16 papers discuss tools such as simulation of experiments, online monitoring of data collection, selection of hits, diagnostics of data quality, data management, and data analysis and structure determination for nanocrystallography and single-particle diffractive imaging.
The two collections represent the first sets of papers to bring under control the data torrent expected from new XFELs. The literature and tools should also prove useful to researchers wishing to enter this new field.
