Abstract
A processing pipeline for diffraction data acquired using the `serial crystallography' methodology with a free-electron laser source is described with reference to the crystallographic analysis suite CrystFEL and the pre-processing program Cheetah. A detailed analysis of the nature and impact of indexing ambiguities is presented. Simulations of the Monte Carlo integration scheme, which accounts for the partially recorded nature of the diffraction intensities, are presented and show that the integration of partial reflections could be made to converge more quickly if the bandwidth of the X-rays were to be increased by a small amount or if a slight convergence angle were introduced into the incident beam.

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser

Yanyong Kang, +71 more
- 30 Jul 2015 - 
TL;DR: The crystal structure of a constitutively active form of human rhodopsin bound to a pre-activated form of the mouse visual arrestin is determined by serial femtosecond X-ray laser crystallography and provides a basis for understanding GPCR-mediated arrestin-biased signalling.

Potential for biomolecular imaging with femtosecond X-ray pulses

TL;DR: Computer simulations are used to investigate the structural information that can be recovered from the scattering of intense femtosecond X-ray pulses by single protein molecules and small assemblies and predict that ultrashort, high-intensity X-rays from free-electron lasers that are currently under development will provide a new approach to structural determinations with X- rays.

Femtosecond X-ray protein nanocrystallography

- 03 Feb 2011 - 
TL;DR: This work offers a new approach to structure determination of macromolecules that do not yield crystals of sufficient size for studies using conventional radiation sources or are particularly sensitive to radiation damage, by using pulses briefer than the timescale of most damage processes.
