Hi,
(Phenix v.1.8.1-1168)
I recently refined a structure using experimental Intensities and compared
it to the same structure refined with calculated structure factors.
I know if you provide intensities Phenix.refine will convert to structure
factors. I am not sure if it runs truncate or what. Anyway, I get this in
the log file which matches my completeness in the scala log file:
Completeness in resolution range: 0.992202
Completeness with d_max=infinity: 0.992164
When I run using structure factors (Truncate run in Scala) I get the
following:
Completeness in resolution range: 0.901282
Completeness with d_max=infinity: 0.901259
Perhaps Scala did not merge anomolous and non-anomolous data?
This does not may a whole lot of sense to me. Is some data thrown out? Can
someone explain?
Thank you.
