I'm not sure how it scales to a large tree, though! For an example
phylogeny of 1,000 tips and a clade of 116 species it ran in the blink
of an idea, so I suppose it's probably OK.
Obviously, I meant to write "blink of an eye." It's been a long day.

Dear Jhonny.
If I understand your problem correctly, this will work in /theory/ --
shown for clade/t5/ through /t9/ in your example.
This works when your tips in a sample form a /clade/ -- but will
otherwise sum the internal edges leading to the internal nodes of all
taxa in a set, while
Dear colleagues, I would like to ask for a little help from you.I have a phylogenetic tree with nine taxa and three samples (see figure below). Each sample has three taxa from the phylogeny. I am interested in extracting the internal branch lengths (corresponding to the ancestors of all tips) that
