Thanks a lot for the quick answer.
> There is no mechanism at the moment, but it is quite easy to implement and it has been on the todo list for a bit. Are you building IMP from source or using a pre-built IMP? If the former, then I can send a patch, if the latter, then we will have to figure out something. Unfortunately, the Selectors aren't properly exposed to python, so we must provide C++ code.
Since I am new to IMP as well as to the problematic it is designed for, I figured out I should start with a high level point of view. Thus : binary install on MAC, and only python access. I will probably switch to a source installation sooner or later.

OK, that was my intuition.
By the way, would you be interested in any testimony with regard to IMP installation ? If so, I could open a thread here just for that.
