unable to download nr database #680

Open juejun14 opened 1 year ago

juejun14 commented 1 year ago

Hi,

thank you creating this tool,

I have a question when building the protein database:

kraken2-build --download-taxonomy --protein --db prot_db --use-ftp --threads 24
Downloading protein accession to taxon map... done.
Downloaded accession to taxon map(s)
Downloading taxonomy tree data... done.
Uncompressing taxonomy data... done.
Untarring taxonomy tree data... done.

I think it has created a protein database, but when I try to download nr with kraken2-build --download-library nr --db prot_db --use-ftp --threads 24

it has showed: nr is a protein database, and the Kraken DB specified is nucleotide

I have search everywhere and I don't find out how to fix it, can anyone help me plz? Thanks,
