WebTreeDist. ‘TreeDist’ is an R package that implements a suite of metrics that quantify the topological distance between pairs of unweighted phylogenetic trees. It also includes a simple ‘Shiny’ application to allow the visualization of distance-based tree spaces, and functions to calculate the information content of trees and splits.

WebDesignating a root imposes a hierarchy on the vertices of a rooted tree, according to their distance from that root. Def 2.3. In a rooted tree, the depth or level of a vertex v is its distance from the root, i.e., the length of the unique path from the root to v. Thus, the root has depth 0. Def 2.4.
