salign.py and align2d_mult.py are for alignment, and evaluate_model.py is for model evaluation. In all of these cases the definition of disulfide bonds is not required. model.patch_ss_templates() adds disulfide bonds in the model, if it is aligned with a template which has a disulfide. This is called automatically for you for 'automodel' so you don't generally need to worry about it.

An example is given in FAQ #3 of how to add specific disulfide bonds in the 'automodel' procedure, using model.patch(). This only applies to the model building step, of course - model_mult.py in your case.
