    46GSAS-II is an open source Python project for determination of crystal structures and diffraction-based materials characterization for crystalline solids on all scales, from perovskites through proteins, using both powder and single-crystal diffraction and with both x-ray and neutron probes. Measurements can be from laboratory, synchrotron, constant wavelength or time-of-flight[#TOF *] neutron sources. It provides structure solution and refinement as well as extensive visualization capabilities. For powder diffraction, GSAS-II also provides preliminary stages of data reduction and analysis, including area detector calibration and integration, pattern indexing, !LeBail and Pawley intensity extraction and peak fitting. Small-angle scattering and reflectometry fitting is also supported. When large numbers of patterns are measured with parametric changes in measurement settings, GSAS-II provides a unique capability to fit all patterns in a single sequential refinement with subsequent parametric fitting.

    68GSAS-II is made available for free use ([https://subversion.xray.aps.anl.gov/pyGSAS/trunk/license2013.txt see license]) with open access to

     9[https://subversion.xray.aps.anl.gov/pyGSAS/trunk/ the source code.] If you use GSAS-II, we encourage you to sign up for the  [https://mailman.aps.anl.gov/mailman/listinfo/gsas-ii GSAS-II mailing list] ([#MailingList see below]). '''Please help us by [#PleaseCite citing it] in your papers'''.

    912We are adding new features to the code quite frequently, so we may break things from time to time ([#Bugs see bug reporting, below]). Be sure to 'Update' frequently to stay abreast of new features and fixes as they are added.

    1114GSAS-II now provides all of the capabilities in the GSAS/EXPGUI programs, which are no longer supported. GSAS/EXPGUI users are encouraged to switch to use of GSAS-II.

    4848  * [wiki:MiscNotes Developer Notes:] ~200 pages of code documentation are on a [https://readthedocs.org/ separate web site.] This is probably not valuable to most users, but code developers should look [wiki:MiscNotes here]. We invite people interested in developing or extending GSAS-II. The code is open source and we are happy to consider collaborations.
