symmetrical fit of maps

Hi all, is there is a way to do symmetrical fit and add symmetrical copies for map to map fitting? The standard symmetrical fitting protocol (measure symmetry. #0...; sym #1 group #0 update true; fitmap...) only works for molecule to map fit.

What you call the “standard symmetrical fitting protocol” looks to me like you just fit one monomer and show the symmetrical copies. Usually we use the term symmetrical fitting to mean that clashes between the symmetry copies are considered and that is done with the fitmap “symmetry” option. But I guess your question is just how to show a bunch of symmetry copies of a map? Unfortunately the sym command only makes copies for atomic models. I can only think of hard ways to do this, like use sym on an atomic model, then copy the position matrices from the atomic model copies to a bunch of map copies using the matrixcopy command. But there isn’t even a command to make N copies of a map. Using Python code would be much easier. Tom
