Below is one way: self.pick_atoms(selection_segment=('147:', '149:'), selection_status='INITIALIZE') self.pick_atoms(selection_segment=('45:', '46:'), selection_status='ADD') self.pick_atoms(selection_segment=('110:', '112:'), selection_status='ADD')

As should be obvious from the example, selection_status needs to be 'INITIALIZE' on the first call, and 'ADD' on any subsequent calls (it could also be 'REMOVE' to remove those atoms from the selection). See http://salilab.org/modeller/manual/node131.html
