Improper

This module defines Improper for dealing with improper information provided by using AtomGroup.setImpropers() method.

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

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

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

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

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

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

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

getSize()[source]: Returns improper size.

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

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