Dear Ape users,

I'be grateful for your help with my ape problems.
I find it difficult to figure out how I can look at the distances between the 
main nodes generated in the phylogenetic tree below. My idea is to extract the 
distances between NBCs to hiMBCs. Somehow looking at the exemplary object tr 
and using tr$edge and tr$edge.length it doesn't seem to be an easy task.


I've tried to add node labels using nodelabels() and edge labels but somehow 
the assigned labels are different then the coordinates stored in the tr$edge 
would suggest (when I look at the tip projection).
Any ideas how I can do it in an automatic way? Is it just a plotting problem 
that the coordinates of edges don't correspond to what I see in the tree.

Thank you very much.
Kind regards,
