I am submitting a structure to the PDB database. The SfCHECK summary report provided by the PDB validation shows an R-factor for model vs structure factors of 0.32, while the R-factor from the refinement program PHENIX is 0.21. I am not familiar with SfCHECK, but I am puzzled how these programs can calculate such different R-factors. I would be thankful for some explanation.
