        The problem, in short, is that I’m trying to call pack_rotamers_setup(). The final argument is an InteractionGraphBaseOP pointer which can’t be instantiated directly in Python.

        I can get a subclass of InteractionGraphBase that I’m interested in, such as ig = DensePDInteractionGraph(n). There doesn’t seem to be any way to dereference this and pack_rotamers_setup() doesn’t like anything but a pointer to the base class as the last argument.

        I can create the correct object by calling ig = InteractionGraphFactory.create_interaction_graph(…), but in order to provide arguments to this method I need to do most of the computation of pack_rotamers_setup(). I’d like to avoid having to reimplement the function if possible.

          I’ve passed this along to Sergey to see if that class exists…this is deeper than most PyRosetta clients need so the direct answer is “probably not yet”.

            Jason, I have looked this up and the problem that ‘pack_rotamers_setup’ function uses last argument as reference for return value. So such functions could not be directly binded in Python. As work-around for this problem I have added two new version of functions pack_rotamers_setup and symmetric_pack_rotamers_setup which will return OP object instead. This code should be available in our binary builds >= 55575.

            Let us know if it worked for you,
