Welcome to Cheetah


Cheetah is a set of programs for processing serial diffraction data data from at free electron laser sources, and which enable taking home only the data with meaningful content.  This is a sanity saver in many serial imaging experiments.

Cheetah is modular and can easily be adapted to any serial imaging data, including data collected using both free electron laser and synchrotron sources using a variety of detectors (including csPAD, pnCCD, AGIPD, Pilatus, Rayonix).



The development of Cheetah has been led by Anton Barty at the Center for Free-Electron Laser Science at the Deutsches Elektronen-Synchrotron, DESY in Hamburg, Germany.
Code has been contributed by: Filipe Maia, Rick Kirian, Thomas White, Chuck Yoon, Carl Nettleblad, Valerio Mariani, Nadia Zatsepin and Andrew Aquila. 
Software has been tested on many beamtimes by numerous people. 

DESY is a research centre of the Helmholtz Gemeinschaft.

See the DESY contact page for official contact details.

The cheetah paper has (finally) been published in the Journal of Applied Crystallography
