An experimental analysis of phylogenetic trees based on topological score

Abstract

In this paper we compare phylogenetic trees obtained from two alignment free techniques based on topological score.Whether the constraint followed by their respective graphical representation will generate the practical(appropriate)evolutionary tree. The trees are compared by giving the score based on topological similarity of the branches between the given trees and optimizing the overall score by paring up branches from one tree to another. Phylogenetic trees are constructed by UPGMA, NJ and MEdistance based method. The distance matrix required by tree construction methods are built from two alignment free methods, probability distribution method and genome space construction with biological geometry. © 2012 Springer-Verlag GmbH Berlin Heidelberg.
