Please see http://salilab.org/modeller/9v1/manual/node22.html for an example. You have three problems with the script above: 1. You need to 'import' the automodel class, which is done in the example script with from modeller.automodel import *

2. You can't name the selection method 'selection_atoms'. It has to be called select_atoms.

3. There is no pick_atoms method; you have to return a selection object. In your case, something like return selection(self.residue_range('37:A', '63:A'), self.residue_range('74:A', '96:A'), self.residue_range('111:A', '133:A'), self.residue_range('153:A', '173:A'), self.residue_range('203:A', '224:A'), self.residue_range('250:A', '274:A'), self.residue_range('287:A', '308:A'))

should be suitable.
