I am trying using Kraken2 to verify viruses in a virome rawdata. For this, I need the nr (NCBI non-redundant protein database).
I did the download of the taxonomy using:
kraken2-build --download-taxonomy --protein --threads 24 --use-ftp --db /data/02_db/kraken2/library/nr/
I did the download of the library using:
kraken2-build --download-library nr --no-masking --protein --threads 24 --use-ftp --db /data/02_db/kraken2/library/nr/
And build the library using:
kraken2-build --build --protein --threads 80 --db /data/02_db/kraken2/library/nr/
However, five days after the beginning of this step, the library-build didn't show any error and didn't finish, I killed the run because I am not sure if will finish.
Please, anyone could tell me if have anything wrong with these commands that I used? Or do I need to include more parameters?
