Hydrogen Bond Acceptor

This module defines Acceptor for dealing with acceptor information provided by using AtomGroup.setAcceptors() method.

class Acceptor(ag, indices, acsi=None)

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

• len() returns acceptor length, i.e. getLength()
• iter() yields Atom instances

getACSIndex()

Returns index of the coordinate set.

getAtomGroup()

Returns atom group.

getAtoms()

Returns acceptored atoms.

getIndices()

Returns indices of acceptored atoms.

getLength()

Returns acceptor length.

getVector()

Returns acceptor vector that originates from the first atom.

setACSIndex(index)

Set the coordinate set at index active.
