yes. it is straightforward with define_symmetry. please ask andras fiser (andras@salilab.org) for modeller-6 so that you do not have problems with modeller4 bugs in the define_symmetry command.

best wishes, andrej

Hello Modellers,

I would like to restrain a loop that is repeated throughout my TARGET to have the same conformation as the first loop conformation where the alignment to the TEMPLATE is good. What is the easiest way to go about this? DEFINE_SYMMETRY?

Any help would be much appreciated,
