FEM: feature-enhanced map [PDF]

Acta Crystallographica Section D Biological Crystallography, 2015
A method is presented that modifies a 2mFobs−DFmodelσA-weighted map such that the resulting map can strengthen a weak signal, if present, and can reduce model bias and noise. The method consists of first randomizing the starting map and filling in missing reflections using multiple methods.
