Webphenix.refine and phenix.model_vs_data use the same code to perform the bulk solvent correction and scaling, so they should report approximately the same R-factors given … WebBecause phenix.refine (like REFMAC) by default substitutes F-calc for missing reflections when calculating 2mFo-DFc and similar map coefficients, ellipsoidal truncation will result in eliminated high-resolution reflections being replaced by F-calc in the maps. This will always make the maps look better, because they are more biased to the model! solve addition and subtraction word problems
