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. -- Yarrow Madrona Graduate Student Molecular Biology and Biochemistry Dept.
