Zitat von Whitfield, Pamela [EMAIL PROTECTED]: Afternoon all After spending over 2 days making up a single file, I'd like to hear some other opinions on the practical aspects of CIF files for structures from powder data. This is partly a moan from trying to get a 11000 line file to pass

Vincent and co Unfortunately I don't yet have the software to do a real VCT data-collection (not sure many people do, hence 'VCT-type'). Until I can do it properly, the best I can do is chop the pattern up into pieces with different count-times (and sometimes step-size at high angles), and

Pam, as the author of the INP format it was not my intention to make your life difficult. Maybe I am wrong but is it the case that we are now supposed to write into CIF more than just primary/raw data. This to me is not what was originally meant for CIF; non-primary data such as logical

The next file I have to make is from a Topas analysis as well. I'm not sure any other program could handle the constraints I constructed for that one (how's that for being controvertial?!). It might be very useful for any future reader of your cif file if you can paste the topas inp file in
