Hi Eugen,
to compute a distance matrix from a phylogeny, you can use the
cophenetic.phylo function in {ape}.
You then have to rescale all distances in you matrix (which are expressed
in million years) by the total depth of the tree:
dist=cophenetic.phylo(tree)
dist2=dist/max(dist)

Florian
Hi folks,
I have phylogeny with absolute branch lengths in million years. How do I
get a distance matrix with values between 0 and 1?
Best,
Eugen
