Hello, I recently looking at the cctbxbb mailing archive and I came across your email response a few months ago : http://phenix-online.org/pipermail/cctbxbb/2014-June/000933.html I was wondering if you could elaborate a bit on how to use the wrappers cctbx.python? I consider myself to be quite a beginner in this area and can't seem to import the same module, import scitbx.array_family.flex *ImportError: No module named boost.optional* When I do I receive the same error about having boost.optional being an import dependency. If you are able to, please be as explicit as possible, I am pretty bad with common conventions and terminology, as I have never studied computer science or any related area formally. Any help would be much appreciated! Sincerely, Garrett Thompson
