Is there a way to create an ultrametric tree in ETE (preferably ete2) for a tree that contains some internal branch attribute labels. I can make one with no attributes set, however I cannot make one when my tree has the attribute faces added to internal nodes.
Any solved this problem before ?
EDIT: More detail
My tree currently looks something like this :http://imgur.com/cn04ylK
I visualize the attributes by grabbing with AttrFace and using the node.add_face function in a custom Treestyle layout function.
