The graphs returned by the Nexus parser are instances that implement
the org.jgrapht.UndirectedGraph interface. Undirected graphs have no
root.

Hi,
I have been trying to use biojava to parse some trees on nexus files
and I have a small doubt:
If there is a rooted tree, how can one know what is the root vertex in
the weighted graph (JGraphT)?
I understand that there is no root if the tree is unrooted, but in
case it is rooted, how to determine the vertex?
Many thanks,
Tiago
