[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.
