Hello all, Having nothing to do with crystallography, I downloaded cctbx only to use the python implementation of the differential evaluation. I am not knowledgeable about the details of the algorithm so I have to ask this question: Is it normal to have population members with coordinates outside of the specified limits? Thanks and regards, Nikolay Mladenov
