gid-taxid returns taxid -1

[melissamlwong]

Hi, I noticed that some converted gid has taxid -1. I think the problem is related to the process of removing GI numbers from the presentations of nucleotide and protein sequence record. These gids are no longer present in gi_taxid_nucl.dmp. I'm switching to accession2taxid.

Dear @melissamlwong,

I believe you are correct. So long as there is a unique sequence => tax id mapping, the rest of the code should work.

Best,
