[chimerax-users] Feature request: replace residues in model with residues from other model

[Eric Pettersen]

Hi Matthias,
	I not familiar with "replace fragment", so I have a few questions.  Is it always the same number of residues in source and target?  Is it always polymeric residues, and the same type of polymer (amino acids, nucleic acids)?  I assume you have to use the backbone conformation of the target.  Are the side chain angles preserved in any way?
	It's possible this could be implemented as sort of a macro around multiple swapaa/swapna commands.

I use it extensively for model building, and would like to request a functionality to replace a residue selection in one model from residues in another model (similar to what is possible in coot via the replace fragment functionality). I am aware that this currently possible by a combination of delete, combine, and changechains, but it would be great if this could be shortcutted.
