Dihedral

This module defines Dihedral for dealing with dihedral information provided by using AtomGroup.setDihedrals() method.

class prody.atomic.dihedral.Dihedral(ag, indices, acsi=None)[source]

A pointer class for dihedrald atoms. Following built-in functions are customized for this class:

len() returns dihedral length, i.e. getSize()
iter() yields Atom instances

getACSIndex()[source]: Returns index of the coordinate set.

getAtomGroup()[source]: Returns atom group.

getAtoms()[source]: Returns dihedrald atoms.

getIndices()[source]: Returns indices of dihedrald atoms.

getSize(radian=False)[source]: Returns dihedral size.

getVectors()[source]: Returns bond vectors that originate from the central atom.

setACSIndex(index)[source]: Set the coordinate set at index active.
