Dear all,
I recall that the set of Rfree reflections should be 500-1000, rather than
5-10%, but I cannot find the reference for it (maybe Ian Tickle?).
I would therefore like to be confirmed or corrected:
Is there an absolute number required for Rfree to be significant, i.e. 500-1000
irrespective of the total number of unique reflections in the data set, or is it
5-10% (as a compromise)?
Thanks and regards,
Tim
