Construction Details

From the helical parameters calculated from the 2 monomers, you can construct an oligomer made of copies of Monomer 1.

If Flatten the oligomer is checked, Heligeom will try to flatten the oligomer to create a ring (with a pitch = 0Å) with a Monte-Carlo algorithm. See the Help page for more information.
