Any ideas on how to use this tool in resolving polytomies in IQ-TREE or RAxML outputs?

[Anto007]

Hi @schultzm, this looks like a very useful tool and thank you for bringing this out. Do you know if this would also work for resolving polytomies in IQ-TREE or RAxML output files? From my quick testing, Budgitree tool (installed via conda on my Ubuntu machine) throws up different errors with both IQ-TREE & RAxML outputs (see below)

budgitree smuggle iqtree.tree > mod_iqtree.tree 
Removing polytomies.

Just in case anyone runs into a similar issue, the below alternative on ete3 python toolkit worked for me with the output treefile from IQ-TREE:

from ete3 import Tree
t=Tree('iqtree.tree', format=1)
t.resolve_polytomy(recursive=True)
t.write(format=1, outfile="mod_iqtree.tree")

Thanks @Anto007. If you could send the trees that were causing you problems, I can run some tests. I have only tested with FastTree output.
