WebFeb 26, 2016 · Neighbor Joining, UPGMA, and Maximum Parsimony Once you have a distance matrix, phangorn provides simple, quick functions for estimating trees from distance matrices using neighbor-joining and UPGMA algorithms, which … Distance-matrix methods of phylogenetic analysis explicitly rely on a measure of "genetic distance" between the sequences being classified, and therefore they require an MSA (multiple sequence alignment) as an input. Distance is often defined as the fraction of mismatches at aligned positions, with gaps either ignored or counted as mismatches. Distance methods attempt to construct an all-to-all matrix from the sequence query set describing the distance between ea…
