org.biojava.nbio.phylo.Comparison

public class Comparison
extends Object

This class provides static methods for the calculation of the percentage of identity between two aligned sequences.

Since 4.1.1 the methods for distance inference in forester are also used in BioJava, so this implementation of percentage of identity is not needed anymore. However, the code is maintained as the own BioJava implementation.
