Tree parse error: unexpected token '_os_78_oe_ropschr02g03077' -- not recognized as a sequence name

[erya-song]

Hi,
I'm running PASTA thus:
run_pasta.py --aligner=mafft --merger=muscle --tree-estimator=fasttree --num-cpus=4 --datatype=protein -i pep/og00090.pep -o 1pasta/og00090

and getting this erro:

PASTA failed because one of the programs it tried to run failed.
The invocation that failed was:
"/home/erya/pasta-code/pasta-master/bin/fasttreeMP" "-quiet" "-wag" "-gamma" "-fastest" "-intree" "/home/erya/.pasta/pastajob/temppkep09an/step0/mincluster/tempfasttreexgyz2k51/start.tre" "-log" "/home/erya/.pasta/pastajob/temppkep09an/step0/mincluster/tempfasttreexgyz2k51/log" "/home/erya/.pasta/pastajob/temppkep09an/step0/mincluster/tempfasttreexgyz2k51/input.fasta"

TypeError: a bytes-like object is required, not 'str'

How can I deal with it?

My best guess is that your sequences have _ as the first character of the name and PASTA is not working well with that. But I am not sure. Can you share with me an alignment that includes _os_78_oe_ropschr02g03077 and 5 other sequences so that I can test?
