In bioinformatics, neighbor joining is a bottom-up (agglomerative) clustering method for the creation of phylogenetic trees, created by Naruya Saitou and Masatoshi Nei in 1987. Usually based on DNA or protein sequence data, the algorithm requires knowledge of the distance between each pair of taxa … See more Neighbor joining takes a distance matrix, which specifies the distance between each pair of taxa, as input. The algorithm starts with a completely unresolved tree, whose topology corresponds to that of a star network, … See more Let us assume that we have five taxa $${\displaystyle (a,b,c,d,e)}$$ and the following distance matrix $${\displaystyle D}$$: First step See more There are many programs available implementing neighbor joining. RapidNJ and NINJA are fast implementations with typical run times proportional to approximately the square of the number of taxa. BIONJ and Weighbor are variants of neighbor joining … See more • The Neighbor-Joining Method — a tutorial See more Neighbor joining may be viewed as a greedy heuristic for the Balanced Minimum Evolution (BME) criterion.
