Hi Scott,
I have an mtz file that has:
I-obs SIGI-obs F-obs SIGF-obs
I want phenix.refine to use F-obs and SIGF-obs, but even though I provide : labels = "F-obs,SIGF-obs"
by default phenix.refine takes I-obs,SIGI-obs. You need to tell phenix.refine explicitly that you want to use F-obs,SIGI-obs.
OK it looks like phenix.refine IS using the F-obs and SIGF-obs, but it is still rejected a couple thousand reflections that have values <= 0. Can phenix.refine be directed to use F-obs <= 0? in particular can either of these flags be given slight negative numbers? input.xray_data.sigma_fobs_rejection_criterion= -0.1 input.xray_data.sigma_iobs_rejection_criterion= -0.1 BTW what does this flag do? input.xray_data.ignore_all_zeros= True Thanks, Scott
