[R-sig-phylo] get branch lengths from distances to root

[Juan Antonio Balbuena]

Hi all This is a simple question: I have a set of ultrametric trees with information on their topology but without branch lengths. On a separate file, I have the distances of each node and leaf to the root. Can someone instruct me on how to to compute the branch lengths of the tree with these two separate bits of information?
