vmd.topology.adddihedral()

Add a dihedral between four atoms with the given indices. No checking for duplicate dihedrals is performed.

Parameters:

• i (int) – Index of first atom
• j (int) – Index of second atom
• k (int) – Index of third atom
• l (int) – Index of fourth atom
• molid (int) – Molecule ID to add dihedral in. Defaults to top molecule.
• type (str) – Angle type. Can be from output of topology.getangletypes(), or can define a new angle type. Defaults to None

Returns:

(int) New number of dihedrals defined in system
