This extension contains a powerful editor to easily twist molecular systems with just a few clicks.

This editor may be applied to any molecular system: nanotubes, proteins, etc., and may be used to rapidly produce large-scale deformations (e.g. unfold a protein, move an alpha helix, position a linker, force a carbon nanotube to buckle, etc.).

Interactive simulation may be applied simultaneously to produce physically-based structures while constraining some atom positions.

Usage

1. Select the Twister editor (Editors menu > Modeling > Twister, shortcut: T).
2. Click on an atom to add a control point (materialized by a yellow sphere) that will constrain the atom's position (Ctrl+Click or Cmd+Click to remove the control point).
3. Press and drag an atom to move and deform a molecule.
