TreeTimeUnknownError: Error: Unexpected behavior detected in multiply function when determining peak of function with y-values '[]'.

[bacterpang]

treetime_issue.tar.gz Hi, I ran TreeTime with 8 different combination of parameters and got normal outputs from 4 of them but failed to do so in the left ones.

For the 4 failed, I got the error messages, which were same as the issue title.

For the 4 that I got normal outputs, the root-to-tip plots did not seem to show a linary regression.

I attached all the files I used and also included the feedback of TreeTime which was name as "slurm-241207.out" .

Could anybody help me with this problem?

Thanks a lot!
