[PyMOL] Default altloc selection

[Ioannis R. <riz...@eb...>]

Hello,

Is there a way to set a default altloc to be selected, if the residue/atom is disordered? I can do this manually with a notation like ‘select foo, obj//chain/resid/atom and alt A’ but if the residue/atom is not disordered, the selection will be empty (I call this through a script for a set of structures so I cannot know if there is disorder beforehand). 

If the ‘and alt A’ conditional is omitted, all the alternative residues/atoms are selected, but I don’t want that. It would be very handy to be able to select a default altloc for these kinds of selections.

Cheers,
