Hi All, 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" I think phenix.refine is seeing the I-obs,SIGI-obs and recalculating the structure factors from those values instead of using the Fs that I provide in the mtz. Is this the case? Other than stripping the I-obs,SIGI-obs from the input mtz, is there a way to force phenix to use my structure factors?
