Hi George, this can happen. If you were refining against reflections from that shell only I'm sure Rfree would be greater than Rwork. I'm not sure how to make sense of comparisons Rfree vs Rwork calculated per resolution shell. Pavel On 1/26/15 1:05 PM, George Devaniranjan wrote:
Hi,
I calculated/validated several PDB structures in Phenix.Validation (GUI)
The R/R-free (overall) is
0.1271/0.1348
Further down I looked at the R/R-free for the highest resolution shell.
Its 0.2538/0.2446
I am curious why the R-free for the *_highest resolution shell_* seems to be LOWER than R (work).
Am I reading the information wrong?
PDB: 3QL9
Thank you, George
