Xtal System Overview

Xtal is a package of over sixty crystallographic programs for calculations ranging from the reduction of raw diffraction intensities, to the solution, refinement and publication of crystal structures. These are applicable to X-ray, neutron and electron diffraction analyses, including charge density studies. The package contains interactive graphics tools and is available as execution modules for most common platforms. For details on how version 3.7 differs from 3.6, look here

Decommissioned Xtal Programs

Our archives contain a number of Xtal programs that are no longer part of the current version. There are a variety of reasons for this. Probably the main one is the macromolecular structure calculations ceased to be supported by Xtal several years ago. Users may wish to check if some of this software is of interest for their work.
