Re: [phenixbb] Different R-free values

Hi Jerome, can you send a log file? What's the PDB code? Differences in R between published and recomputed values are expected but in this case it is strange that Polygon and phenix.refine report different values since they use the same routines to compute them.

Dear all: I find that phenix.refine reports a higher starting R-free than those stated for structures downloaded from the PDB. For instance, the R-free stated in the PDB = 0.287, using Polygon = 0.2880, but the Start R-free from phenix.refine = 0.3114 Is this usual, or is something seriously wrong? Thank you, -Jerome
