"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 (e.g., species … 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 First joining We calculate the See more There are many programs available implementing neighbor joining.
