Welcome to the diffpy-users Google group, home to discussions about data-analysis and modeling software for atomic pair distribution function (PDF) analysis. In particular, about the programs at Diffpy.org, such as PDFgui, but there are also more general pearls of wisdom about PDF and PDF analysis from members of the community.
If you have a bug report or feature request about any of the software programs please post it to the diffpy-dev user group. Anything else on these topics, please search the database here and if it isn't covered.......raise a question. We try and respond as quickly as we can!
