Hi,

I’m trying to run identify_chimeric_seqs.py script using the usearch61 option.

My script is as following:

identify_chimeric_seqs.py -i seqs.fna -m usearch61 -o usearch_checked_chimeras -r gg_13_8_otus/rep_set/97_otus.fasta

And I’m getting the following error:

Traceback (most recent call last):

About this error, what can I do?
