Shay,
Rietveld refinement is a method for crystal structure refinement, not crystal structure solution. You need to have a starting model… If you are new to the Rietveld method, there are a number of nice resources available, including: http://www.aps.anl.gov/Xray_Science_Division/Powder_Diffraction_Crystallography/ http://www.ccp14.ac.uk/solution/gsas/gsastutorials.html Best, Matt Beekman, Ph.D. Assistant Professor of Physics Department of Natural Sciences Oregon Institute of Technology 3201 Campus Drive Klamath Falls, OR 97601 Tel: 541-885-1940 Fax: 541-885-1849 Email: <mailto:matt.beek...@oit.edu> matt.beek...@oit.edu Web: <http://www.oit.edu/faculty-staff/resources/home-pages/natural-science/matt-beekman> http://www.oit.edu/faculty-staff/resources/home-pages/natural-science/matt-beekman From: rietveld_l-requ...@ill.fr [mailto:rietveld_l-requ...@ill.fr] On Behalf Of Shay Tirosh Sent: Saturday, December 13, 2014 1:15 AM To: rietveld_l@ill.fr Subject: Re: Problem in EXPGUI Thanks Rietvelders. I will follow your suggestions. Is there any YouTube tutorial that show directly on EXPGUI how to refine an unknown structure?

I was unable to get the Histogram tab, although I followed and defined the Phase first using a given CIF. I also tried to bypath the problem by using one of the EXP file (Old.EXP, New.EXP) without success. Still the Histogram tab absent. Did you encounter the same problem?Are there any problems with windows 7 and 8?
