Dear Lee, If you have data as (.dat) for GSAS, TOPAS can read this file in the option GSAS CONST data files (.). However, you can convert .asc to .xrd and then to read it with POWDERX and save it as GSAS (.dat)
Best Regards, Mario Macías Universidad Industrial de Santander Colombia ------------------ I have a question for the list... I have some ToF data from GEM ISIS as both a .gss and a .asc file. I have managed to import and refine this using GSAS but am having some difficulties importing into TOPAS. Does anyone have some advice please on maybe file exchange or getting this file into the correct format to be read by TOPAS. Or do I need to contact GEM to issue me with a different file type?
