    3 GSAS-II is an open source Python project that addresses all types of crystallographic studies, from simple materials through macromolecules, using both powder and single-crystal diffraction and with both x-ray and neutron probes. Measurements can be constant wavelength (or in the future, neutron TOF.) At present, code is being developed for all the various steps in diffraction analysis, such as data reduction, peak analysis, indexing, structure solution and structure refinement. The source code can be found at https://subversion.xray.aps.anl.gov/pyGSAS/trunk/

    5 At present GSAS-II can be used for processing of area detector data, peak fitting, auto-indexing, structure solution, Pawley and Rietveld fitting. Many of the nice features of GSAS are present and some things work much better than in GSAS, but other features are yet to come. At this point only x-rays and constant wavelength neutrons are implemented (no TOF). The GUI is self-documenting with help pages for every GUI page. The code is changing on a regular basis, so expect things to break from time to time and you should 'Update' frequently to stay abrest of new features as they are added.
     5At present GSAS-II can be used for processing of area detector data, peak fitting, auto-indexing, structure solution, Pawley, Rietveld and small-angle scattering fitting. It can be used with large collections of related datasets for repeated (sequential) refinements and for parametric fitting to thise results. Many of the nice features of GSAS are present and some things work much better than in GSAS, but a few features are yet to come. At this point only x-rays and constant wavelength neutrons are implemented (TOF is currently being implemented). The GUI is self-documenting with help pages for every GUI section. The code is changing on a regular basis, so expect things to break from time to time and you should 'Update' frequently to stay abreast of new features as they are added.
