Yes, there are a few different formats of data in the Lytle database. As far as I can tell, the files with 'CUEDGE START STOP BEG FSCTS: ...' do not include a "known" d-spacing or steps-per-degree, but tend to use Si(111) (dspace = 1.9202). You didn't include the rest of the file or say which file you're trying to use, so it's impossible to tell what problem you're having. Well actually what I was trying to do was to obtain a meanigful value for motor step 168620 (CUEDGE, which I included in the header), and with d-space set to 1.92017 and step-per-degree equal to 8000 you get CUEDGE =8977 eV, so set(dspace=1.92017, stpdeg=8000) fixed my problem For further files what I needed was possible values for stpdeg, which you already give me. Thanks Matt and the community,and also thanks for the macro too! Regards, Marco
