[modeller_usage] extended conformations

Dear all,

I am trying to construct a model with two chains, the conformation of the template is extended helix, However, the conformations of the model I got were folded, the C-terminal is very close to the N-terminal. It is not extended which is what I want.

How can I do to make sure that the conformation of the models are extended?

All the best, Qinghua
