[chimerax-users] Copy attribute value from one attribute to another

[Eric Pettersen]

The Python would be:

for m in session.models:
	if hasattr(m, 'residues'):
		for r in m.residues:
			r.atoms.bfactors = getattr(r, 'seq_conservation', 0.0)

Which you could put into a file with a '.py' suffix, and execute in ChimeraX simply by opening it.

The idea would be to save a pdb file with the conservation stored in bfactor (for sharing). In this case I guess there is the issue that one is an atom attribute and the other is residue attribute but one could assign all atoms of the residue the same value.
