Cross-term

This module defines Crossterm for dealing with crossterm information provided by using AtomGroup.setCrossterms() method.

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

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

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

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

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

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

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

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

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

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