RuntimeError: Failed to parse newick tree

[nt365]

I keep receiving the error found in the "slurm.hal0082.131857976.err.txt" file. My newick tree is in the "drosophila.txt" file. I am unsure of what is incorrect about the tree.

Any feedback here would be appreciated.

Hello! Did you managed to solve the problem? I'm getting the same error, and I already verified the correct structure of the newick tree using this tool: https://github.com/ila/Newick-validator

Cactus only wants leaf names and branch lengths. It doesn't know how to correctly handle things like 0.51:0.01395

Thank you for the quick reply. Unfortunately, I tried to run cactus using a simple newick tree with and without branch lengths. This is the error I got:

Oops, didn't notice which repo this was in. Only this version of cactus is supported https://github.com/ComparativeGenomicsToolkit/cactus

Hi everyone,

I am using TreeCluster.py program and i am getting this error. File "/usr/local/lib/python3.8/dist-packages/treeswift/Tree.py", line 1455, in read_tree_newick raise RuntimeError("Failed to parse string as Newick: %s"%ts)

How do I solve this problem?
