Structure refinement in PHENIX - University of Oregon

WebThe use of “Refinement” is similar - with the addition of using a map. The map used to refine the structure is set by using the “Refine/Regularize Control” dialog. If you have read/created only one map into Coot, then that map will be used (there is no need to set it explicitly).
