Error: not a valid variable identifier in call to FindRoot(models.generic.SetBranchLength.t,

[eiverso]

Hello,

I'm a online GUI user of the datamonkey RELAX servers, so forgive me if this is something that would be obvious to a person who had installed RELAX themselves.

I've got a tree in a format and of a size that I've used successfully before, but something is going wrong this time, maybe with a particular taxon name. The tree is attached, along with the error file. Basically, seemingly because of one taxon, I always get this error after about 2 minutes:

### Fitting the general descriptive (separate k per branch) model Error: 'cqdenONB.tree_id_0.30_15_27_27_C46_R089_TRA_GEE.t' is not a valid variable identifier in call to FindRoot(models.generic.SetBranchLength.t,

Followed by basically the entire tree with a bunch of strange notation. "30_15_27_27_C46_R089_TRA_GEE" is the name of the first taxon in the user-defined tree, read from left to right. Although, in actuality, it is "30_15_27_27_C46_R089_Tra_gee" with lower-case letters.

Any ideas about what's going wrong?

Note: the alignment, with user-defined tree at the bottom, is renamed .txt, because apparently github doesn't allow you to upload a .fas???

Thanks!

Dear @eiverso,

Try updating the headers to start with a character instead of a number. HyPhy has difficulty understanding labels that start with a number.

Best, Steven
