Neighbor joining tree 意味

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 … 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. 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.

WebMay 17, 2009 · Neighbor Joining (NJ) is a so-called distance-based method that, thanks to its good accuracy and speed, has been embraced by the phylogeny community. It takes the distances between n taxa and produces in Θ ( n 3) time a phylogenetic tree, i.e., a tree which aims to describe the evolutionary history of the taxa.
