Dear Marcelo (& others), GSAS should do texture (sph. harmonics) with "film" data (or image plate) powder data. Image needs to be divided up in to 'pie' sections & integrated to give a sequence of patterns about the azimuth. The read them as separate "histograms" in GSAS & give each the appropriate azimuth angle (set that in histogram editing). Azimuthal angle is right handed looking away from source & zero is in right side horizontal facing the source. Hope that's clear. GSAS will not read cif files. Bob Von Dreele

I am trying to perform some refinement with Rietveld using GSAS and I am not sure if by loading the CIF or the CEL files already takes that into account. Can anyone help me, please? I try to enter manually the values in EXPGUI but really am not sure which way is the correct. Thank you. I am also having a hard time fitting synchrotron data from a film (highly textured) and sometimes I wonder if it is possible. If someone can give a hint, I would really appreciate it, even if the hint is: not possible!!! Marcelo ========================================== Marcelo J.
