Profex - Open Source XRD and Rietveld Refinement
Profex is a program for Rietveld refinement of powder X-ray diffraction (XRD) data based on the refinement kernel BGMN. It can be used for phase identification, phase quantification, structure refinement, and provides a large number of convenience features. Profex runs on Windows, Linux, and Mac OS X operating systems and is available as free software.
Using this programme, many researchers have been very successful in participating in the Reynolds Cup.
