WebAn important part of the code was translated from FORTRAN code from the neighbor-joining program written by Naruya Saitou and by Li Jin, and is used with the kind permission of Drs. Saitou and Jin. Neighbor constructs a tree by successive clustering of lineages, setting branch lengths as the lineages join. The tree is not rearranged thereafter. WebSaitou, N. and Nei, M.

Webthe neighbor-joining method. The fundamental idea of distance matrix methods is that we have an observed table (matrix) of distances (Di)), and that any particular tree that has branch lengths leads to a predicted set of distances (which we will denote the d ij ). It does so by making the prediction of the distance between two species by adding 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 $${\displaystyle D}$$ See more The main virtue of NJ is that it is fast as compared to least squares, maximum parsimony and maximum likelihood methods.
