Re: [phenixbb] does phenix.refine ignore F-obs, SIGF-obs?

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.

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.

Yes, this is what it does.

Other than stripping the I-obs,SIGI-obs from the input mtz, is there a way to force phenix to use my structure factors?

Yes, specify them explicitly: input.xray_data.labels="F-obs" Let me know if you have any problem or questions! Pavel.
