Dear Sir , I am trying to build a model where the template is a homo-6-mer. What changes do I make in the MyModel class? # Override the 'special_restraints' and 'user_after_single_model' methods: class MyModel(automodel): def special_restraints(self, aln): # Constrain the A and B chains to be identical (but only restrain # the C-alpha atoms, to reduce the number of interatomic distances# that need to be calculated): s1 = selection(self.chains['A']).only_atom_types('CA') s2 = selection(self.chains['B']).only_atom_types('CA') '''s3 = selection(self.chains['C']).only_atom_types('CA') s4 = selection(self.chains['D']).only_atom_types('CA') s5 = selection(self.chains['E']).only_atom_types('CA') s6 = selection(self.chains['F']).only_atom_types('CA')''' self.restraints.symmetry.append(symmetry(s1, s2,1.0)) def user_after_single_model(self): *Should I add restraint for each chain ??* *KIndly help me*

*Thanks and Regards* *Anwesha*
