XPREP (Bruker AXS GmbH) was used to prepare data for substructure searches. Jun 11, 2025 · UPGMA (Unweighted Pair Group Method with Arithmetic Mean) is a hierarchical clustering algorithm widely used in bioinformatics for constructing phylogenetic trees and analyzing the similarity between biological sequences or samples. Finally, notice that UPGMA always produces an ultrametric tree, i. It also has a weighted variant, WPGMA, and they are generally attributed to Sokal and Michener. An interesting aspect of this method is that it produces a tree that mimics a species tree, with the branch lengths for two OTUs being the same after their separation. Today most phylogenetic trees are built from molecular data: DNA or protein sequences.
