Hi Sarah, Yes, you can do a "fit" without any 'guess'ed values to get a theoretical XAFS spectra. In artemis, open any data file, then the desired feff calculation. You can change the definitions for any of the path parameters in the page for each path, and the values for the variables in the 'Guess, Def, and Set Parameters' page. Then, under the 'Data' menu, you can choose 'Sum Paths (no fit) for this data'. You could also simply change all 'Guess'es to 'Set in the 'Guess, Def, and Set Parameters' page and do a "Null Fit". I don't know of a way to do this in artemis without a data file, but that doesn't mean you have to look at the data.... Hope that helps! --Matt
