automodel.rand_method -- control initial model randomization

Description:

This is used to randomize the initial model before producing each final model. (If set to None then no randomization is done, and every model will be the same.) You can provide your own function for this purpose, or use one of the functions in the randomize module -- randomize.xyz to randomize all coordinates, or randomize.dihedrals to randomize dihedral angles.
