Rooting a phylogenetic tree

WebA phylogenetic tree is constructed by using the UPGMA method with pairwise distances. More specifically, the seqpdist function computes the pairwise distances among the considered sequences and then the function seqlinkage builds the tree and returns the data in a phytree object. WebTwo methods are provided to assist in the automatic rooting of phylogenetic trees. Since tree nodes contain relative age information (based on the species code autodetection), the same relative age dictionaries can be used to detect the farthest and oldest node in a tree to given sequences.
