Andrea,

The 'ape' package in R can read nexus file trees. You can then calculate
the matrix of patristic distances using the 'dist.nodes' command.

Best,

Dean

Dear morphometricians,
please, does anyone know about programs for computing pairwise distances
among all nodes in a tree?
I am looking for something which I can load a nex/phy tree in and get
distances not only between the tips of the tree but also between these and
internal nodes and among the internal nodes themselves.
Thanks for your help.
Cheers

Andrea
