Hi Chimera Team, Is it possible/does a function exist to fit one structure inside the calculated surface of another? To be clear, i don't mean inside a density map, I mean an MSMS surface calculated from a PDB inside chimera itself. I have 2 proteins that are sequentially very different, but I suspect fulfilling the same role. They don't overlay via MatchMaker well, but they look to have quite similar space occupation, so I'd like to see how well they fit in one anothers 'map'. Any alternative suggestions appreciated!
