GSAS & EXPGUI
The General Structure Analysis System (GSAS) is a software package
to fit structural models to x-ray and neutron diffraction
data. It can be used with both single-crystal and powder
diffraction data (Rietveld analysis). EXPGUI
is a Graphical user interface to GSAS. Both are distributed
here as a combined package.
Home for GSAS and EXPGUI is now at ANL
CMPR & LOGIC
CMPR is a multipurpose program that can be used for displaying & scaling
diffraction data, manual- & auto-indexing, peak fitting and other nifty stuff.

The CIFTOOLS includes two programs:
is used to plot of Rietveld results from pdCIF files, particularly for
is used to create browse through and edit CIF files.
It may be used with all types of CIF files, including mmCIFs.
At this time, a newer test release of these programs with expanded capabilities for dictionary use is available for windows (only). This release will be soon packaged for the other platforms.

|IsoDEC is of interest for diffraction stress determination. It calculates diffraction elastic constants, stress from measured d-spacings or d-spacings from stress.|
