> It's likely I have much molecule that simulated, then I just want to lock one of x-axis of an atom. Use the "Select" tool to select an atom or atoms. Go to Extensions -> Molecular Mechanics -> Fix Selected atoms. If you just want to lock the x-axis, then choose "Constraints…" instead of "Fix Selected" and freeze the x-coordinate. (It's possible.) Hope that helps, -Geoff |
