Problems about human germline sequence

[LLei2]

While using humanization module at https://biophi.dichlab.org/, I found the sequence of IGKV2-30*01 was different from the sequence from http://www.imgt.org/download/GENE-DB/IMGTGENEDB-ReferenceSequences.fasta-AA-WithoutGaps-F+ORF+inframeP .The second sequence was copied from the biophi web page.

Maybe there are some errors with your human germline V and J gene sequences.

Hi @LLei2, thanks for reporting this. Looks like an issue with ANARCI numbering, our IGKV2-30*01 sequence is identical to GENE-DB but it gets scrambled during grafting. We'll look into this.

Ok, this seems like an ANARCI issue indeed. I fixed it on the public server by installing an older version of ANARCI: conda install anarci==2020.04.23. Can you try submitting at https://biophi.dichlab.org/ again please?

We'll need to submit an issue to the ANARCI repo, not sure what change introduced this error.

After resubmitting, the returned results make sense. Thanks for fixing this issue.

Great, thanks. Closing this now, since it seems like an ANARCI issue. I submitted an issue report to the ANARCI repo: oxpig/ANARCI#17

BioPhi will now require ANARCI version from 2020 until this is resolved.
