        I was originally using the DockMCMProtocol in  PyRosetta.monolith.ubuntu.release-56 for ligand docking, however since downloading PyRosetta.monolith.ubuntu.release-84, a segmentation fault is returned when running the identical script that was used in release 56. I was wondering if anybody else has experienced the same issue or whether it is a known bug?

          Can you post the script, or at least a simple version of it?  DocMCMProtocol is the main docking protocol and is tested in Rosetta, so it should be fine in PyRosetta.  It may be an input thing or something that changed with the foldtree.
