[cctbxbb] model selection

Currently model class has three selection methods: def selection(self, selstr, optional=True): def select(self, selection): def iselection(self, selstr): which is hideously confusing with zero chance to remember, and also inconsistent with the rest. Most objects in cctbx  have ".select(self, selection)" methods, while being inconsistent about what they expect: iselection or boolean selection as "selection" argument. Some smart ones though can take both int or bool selections (figure out type automatically, which is trivial). Can we consolidate all three into one ".select()" that would allow taking bool or int or str? Or you think there are philosophical arguments against it? Pavel On 8/16/18 15:00, CCTBX commit wrote:
