jD2Stat: an alignment-free tool for generating pairwise distances of molecular sequences


Overview

jD2Stat (previously known as JIWA*) is a Java package that utilises a series of D2 statistics to extract k-mers (subsequences at defined k length) from a set of biological sequences, and generate pairwise distances for each possible pair. This distance can be used directly for phylogenetic inference using neighbour-joining.
