-- I'm modellling an Immunoglobulin-type domain. When generating the homology models using automodel, the beta sheet structure in the models seems to be disturbed when compared to the template. This is obviously an error in the model as the besta-sheets are conserved in every related family member. As expected, the problem occurs in the loop building and energy minimization steps, as i do not see the loss of beta-sheet structure when using "a.make("exit=2")". What is the best way to avoid loss of beta-sheet structure, e.g. by tethering, restraining sec. structure ...?
