浅谈Neighbor-joining 在生物信息学中,邻连法(Neighbor-joining)是由 Naruya saiitou 和 Masatoshi Nei 于1987年提出的一种自下而上(聚集性)的聚类方法,用于创建系统发育树。该算法构建树通常用于基于 DNA 或蛋白质序列数据,需要知道每对类群(例如,物种或序列)之间的距离,以形成树。 邻接法以距离矩阵作为输入,表...
It is nearly 20 years since the landmark paper (Saitou and Nei 1987) in Molecular Biology and Evolution introducing Neighbor-Joining (NJ). The method has become the most widely used method for building phylogenetic trees from distances, and the original paper has been cited about 13,000 times...
回到最初的问题上,由于Q-criteria只是考虑了Long branch attraction的影响,因此NJ方法并不能应用到更一般的情况,相反UPGMA方法基于分子钟假设(在度量层面相当于ultrametric,在树的层面相当于叶节点深度相同的有根树)。就是说,尽管UPGMA基于的假设是NJ的子集,但在更一般度量的情况下,反而是UPGMA 方法具有更好的效果。...

Neighbor-Joining (NJ) was introduced by Saitou and Nei [1] based on the idea of minimizing the sum of branch lengths in the final topology. The input is an n×n matrix D with pairwise distances among taxa in U. If the n taxa in U form a star (Fig. 1a) and i and j are group...
Neighbor-joining is a well-established hierarchical clustering algorithm for inferring phylogenies. It begins with observed distances between pairs of sequences, and clustering order depends on a metric related to those distances. The canonical algorithm requiresO(n3) time andO(n2) space fornsequences...
