Marking clades in tree based on distance matrix cut-off

Question

[hakon.kaspersen]

I have generated a phylogenetic tree, and have calculated the patristic distances from that tree. What I want to do is to identify which clades in the tree are below a given patristic distance threshold, and mark them in the tree (i use ggtree here).

Note that the tree is not generated from patristic distances, but the patristic distances are generated from the tree. I therefore have two objects: The tree and the patristic distance matrix.

Is there any package or function out there to do this?
