Hi Lindsey, The following should work:
select sele, obj1 and not (obj1 like obj2) or to match all identifiers, not only resi/name: select sele, obj1 and not (obj1 in obj2) There are also actual "diff" and "symdiff" commands available from PSICO (https://pymolwiki.org/index.php/Psico). Try this: run https://raw.githubusercontent.com/speleo3/pymol-psico/master/psico/selecting.py symdiff obj1, obj2 Hope that helps. Cheers, Thomas On 23 Jan 2017, at 14:00, L.
