In this work, a novel parallel Unweighted Pair Group Method with Arithmetic Mean approach on multiple Graphics Processing Units is proposed to construct a phylogenetic tree from extremely large set of sequences.

UPGMA (unweighted pair group method with arithmetic mean; Sokal and Michener 1958) is a straightforward approach to constructing a phylogenetic tree from a distance matrix. It is the only method of phylogenetic reconstruction dealt with in this …

Another hierarchical clustering algorithm that is commonly used in bioinformatics and evolutionary biology is the Unweighted Pair Group Method with Arithmetic Mean (UPGMA). The steps involved in the UPGMA algorithm:

2002年10月31日 · This page shows just one method (UPGMA clustering) for calculating phylogenies from molecular comparison data. There are many other methods (bootstrapping, jack-knifing, parsimony, maximum likelihood, and more), and these may be more appropriate to use in given circumstances.

2019年3月26日 · One commonly used approach for averaging the distances is the Unweighted Pair Group Method with Arithmetic means (UPGMA). Formal Definition When considering clusters $S$ and $T$, the UPGMA measure is equal to the average of the distances taken over all pairs of individual elements $s \in S$ and $t \in T$.

The program calculates a similarity matrix (only for option a), transforms similarity coefficients into distances and makes a clustering using the Unweighted Pair Group Method with Arithmetic mean (UPGMA) or Weighted Pair Group Method with Arithmetic Mean (WPGMA) algorithm.

2018年10月25日 · Two related methods for infer phylogenetic trees from multiple sequence alignments (MSAs) are the Unweighted Pair Group Method with Arithmetic Mean (UPMGA) and the Weighted Pair Group Method with Arithmetic Mean (WPGMA).

UPGMApy is a basic implementation of the UPGMA (Unweighted Pair Group Method with Arithmetic Mean) algorithm, one of many used in bioinformatics (phylogenetics) for constructing evolutionary trees. (The typical data set is a matrix of molecular comparisons between species.)

2019年1月27日 · Given the differences between a set of organisms, we must create a phylogenetic tree. There are a variety of ways of making a cladogram starting from this data, one of which is the Unweighted Pair...

The UPGMA (Unweighted Pair Group Method with Arithmetic Mean) method (Sneath and Sokal, 1973) is a simple agglomerative hierarchical clustering method to produce a dendrogram from a distance matrix.
