XDS

Info

XDS is the most widely used software for processing X-ray diffraction data from single-crystal experiments. Developed by Wolfgang Kabsch at the Max Planck Institute for Medical Research, Heidelberg, Germany. Free for academic use but closed-source (binary-only distribution). Handles indexing, integration, scaling, and merging.

Closed source

Unlike DIALS (fully open-source) and CCP4 tools, XDS is distributed as binaries only. This is a significant governance/access point. Wolfgang Kabsch is the sole developer and maintainer, creating a bus factor of 1.
