Question about sylph-tax with custom database

[lingrongjin]

I followed https://github.com/bluenote-1577/sylph/wiki/Incorporating-taxonomic-information-into-sylph-with-sylph%E2%80%90tax to profile against GTDB220 and my own MAGs. However, I got this error when running sylph-tax:
Reading metadata: ['GTDB_r220', '../n620_taxonomy.tsv'] ...
Traceback (most recent call last):

I'm wondering if you have any idea what might be causing this error. I double checked that my taxonomy file does not include "t__STRAIN". However, many of my MAGs were novel at genus or species level (with g__;s__ for gtdb classification). I'm not sure if this might be the reason and if so should I modify the taxonomy file to manually assign ids to the unassigned genus/species rank?

@lingrongjin can you paste a few lines of your custom taxonomy file? see https://sylph-docs.github.io/sylph-tax-custom-taxonomies/ for the latest version of the document. You should not be including t__STRAIN.

Perhaps manually assigning ids would help...
