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. WebThe "patristic distance" between two tips and/or nodes is the shortest cumulative branch length that must be traversed along the tree in order to reach one tip/node from the other. Given a list of tips and/or nodes A, and a 2nd list of tips and/or nodes B of the same size, this function will calculate patristic distance between each pair (A[i ...
