sci-chemistry XDS-Viewer is a program for viewing X-ray diffraction and control images in the context of data processing by the XDS Program Package (external link). Potential users of the software are scientists working in the field of crystallography. The XDS-Viewer is a standalone program which has build-in support for a subset of the Crystallographic Binary File Format CBF (external link). Other file formats are supported through an external convertion program that comes with XDS. XDS-Viewer will automatically invoke the convertion program for images other than CBF.
