In additional to calculating patristic distances, it provides plots for any combination of matrices, calculates commonly used statistics, allows data such as isolation dates to be entered and reorders matrices with matching species or gene labels.
The Geographic Distance Matrix Generator is a platform-independent Java application that implements the same powerful suite of spherical functions as the Perpendicular Distance Calculator to compute all pair wise distances from a simple list of geographic coordinates.
Use this program to create a dendrogram from (a) sets of variables, (b) a similarity matrix or (c) a distance matrix.
Distance-based phylogeny problem. Input: distance matrix of pairwise distances for N species. Goal: find a tree consistent with the distance matrix. This means that the sum of edge lengths connecting each pair of leaves ij corresponds to a distance Mij.
17 mar 2021 · A distance matrix has to satisfy additional properties in order to correspond to some weighted tree. In fact, there are two models that assume special constraints on the distance matrix: Ultrametric: For all triplets (a, b, c) of leaves, two pairs among them have equal distance, and the third distance is smaller; i.e. the triplet can be ...
