[chimera-dev] Get Molecule Index in Model Panel

[Eric Pettersen]

Hi Pablo,
	The “model IDs” aren't even necessarily integers, for instance the model ID of the first member of an NMR ensemble is 0.1 .  The easiest way to get the atom spec you are trying to generate is to call str() on the model.  For instance if m is a variable holding model 0, then str(m) returns “#0”.  So your indexes.append() call becomes:

	indexes.append(str(molecule))

and you don’t even need to use enumerate().
