Hi Folks Had a vague comment handed my way that "xia2 assigns too many free reflections" - I have a feeling that by default it makes a free set of 5% which was OK back in the day (like I/sig(I) = 2 was OK) but maybe seems excessive now.
This was particularly in the case of high resolution data where you have a lot of reflections, so 5% could be several thousand which would be more than you need to just check Rfree seems OK. Since I really don't know what is the right # reflections to assign to a free set thought I would ask here - what do you think? Essentially I need to assign a minimum %age or minimum # - the lower of the two presumably? Any comments welcome! Thanks & best wishes Graeme
