CrystFEL - Data processing for serial crystallography ===================================================== Copyright © 2012-2021 Deutsches Elektronen-Synchrotron DESY, a research centre of the Helmholtz Association. See AUTHORS as well as individual source code files for full details of contributors. Introduction ------------ CrystFEL is a suite of programs for processing (and simulating) Bragg diffraction data from "serial crystallography" experiments, often (but not always) performed using an X-ray Free-Electron Laser. Compared to rotation data, some of the particular characteristics of such data which call for a specialised software suite are: * The sliced, rather than integrated, measurement of intensity data. Many, if not all reflections are partially integrated. * Many patterns (thousands) are required - high throughput is needed. * The crystal orientations in each pattern are random and uncorrelated. * Merging into lower symmetry point groups may require the resolution of indexing ambiguities. Getting started --------------- See INSTALL.md for installation instructions. The best way to get started, after installation, is to run command ```crystfel``` to start the graphical user interface.
