[Chimera-users] Straighten a helix

I would like to straighten a helix in a complex composition of helices, i.e., at least some of them may vdw interact with each other if moved. Therefore, I plan to let molecular dynamics (MD) changing dihedral angles at the pivot amino acid. I wonder whether chimera might aid through "adjust torsion" or other tool. If not else to provide alternative conformations for input to MD and see if the adjustments converge. Bending of the helix occurs along 5 amino acids, the central one probably the pivot.
