nt Database question #764

Closed 1023011930 closed 8 months ago

1023011930 commented 8 months ago

Dear sir or madam, I am downloading the index from "https://benlangmead.github.io/aws-indexes/k2". I noticed that there is a newer nt Database (400+ GB), so I am downloading "k2_nt_20230502.tar.gz", and I was wondering how to build the db with kraken2-build after downloading this file, as I understand it. In my understanding, there is no "k2_nt_20230502" option in "--download-library TYPE", only "nt". image I'd appreciate it if you could answer my questions.

If you download any index from the aws-indexes, you do not need to rebuild the database. The databases provided are already built. You can run kraken2 directly with those databases.

Thanks for your reply, unfortunately I got an EOF error when I unzipped the file again, probably because the downloaded file was incomplete. Maybe "wget" is not a good way to download large files!
