reduceStructure: Structure reduction of an object of class 'Knot'

In FedericoComoglio/Rknots: Topological Analysis of Knotted Proteins, Biopolymers and 3D Structures

Description

Apply the Alexander-Briggs reduction or the Minimal Structure Reduction algorithm to a knot or a link stored in a 'Knot' object.

Usage

	reduceStructure(knot, algorithm = 'AB')

Arguments

knot	an object of class 'Knot'
algorithm	'AB' (default) for the Alexander-Briggs reduction scheme, 'MSR' for the Minimal Structure Reduction algorithm.

Value

an object of class 'Knot' containing the reduced structure
