Hi,

Would it be possible to add an option to fitmap (in either/both chimera/chimerax) to restrict the spatial frequencies used for fitting? That is, to fit gaussian filtered versions of the input maps behind the scenes, but apply the resulting transform to the unfiltered maps? Filtering maps to say 15 Å gives a much better radius of convergence in my experience - much less prone to getting stuck in local minima.

...

Cheers
