Subject: How to change R-free set? From: Jason C Porta jporta {- at -} UNMC {- dot -} EDU Date: 2008-06-17
Hi all,
I am currently refining a high-resolution structure that has many reflections (~180,000). I would like to halve the R-free set from 5% to 2.5%, and am unsure how to do so. Any advice will be greatly appreciated.
