Help for GSAS-II

This and the web pages referenced below, provide documentation for use of the GSAS-II graphical user interface (GUI). The information is organized largely to follow the different sections of the GUI and is usually accessed via the "Help" features in GSAS-II: Help on specific sections of GSAS-II can be accessed from the "?" button (yellow on some computers) in the upper right corner of the data window, or from the Help command. The GSAS-II graphics window and in other locations of the program also offer access to context-specific help information.

A single file containing all GSAS-II web pages is available as a PDF document (note: ~100 pages, please don't print it.)

An index on the topics covered in these help pages is given below.
