An application for the single-crystal analysis and the Rietveld analysis used in X-ray and neutron diffraction experiments. This application determines crystal structure models of materials from X-ray and neutron diffraction data on single-crystal and powder samples. It supports Windows, Mac OS, and Linux. Graphical user interface (GUI) can be used.
A tool to extract numerical data from graphs in pictures. Operations of GSYS is based on the GUI and it is easy to generate the numerical data from the given graph.
