Problem with a tree for ClonalFrameML

Question

[little_more]

I'm trying to run ClonalFrameML using a tree:

But I get an error:

Single descendant found
ERROR: convert_NewickTree_to_marginal_tree(): Number of nodes (20) and number of tips (10) incompatible with a strictly bifurcating rooted tree

What's the problem here?

[Joe]

Something about the internal node structure of your tree must be wrong, somehow. For a perfectly bifurcating tree, there should be 2n - 3 nodes in the tree. You somehow have 20 it seems, but with 10 tips, you should only have 17.

[little_more]

Yeah, I understand that. But I don't see any problem in the tree. It seems bifurcating enough to me. :-)

[Joe]

How did you generate the tree?
