    Hey,

    I have small comment regarding this seqment:

    A) Downloading and using an ncbi-curated database.
    The databases can be downloaded using the update_blastdb script. As an example I will download a non redundant protein database which is referred to as ‘nr’:
    cd $BLASTDB
    sudo update_blastdb –passive –timeout 300 –force –verbose nr
    Here you are not runing script that you mentioned above, but you are calling instaled program.

    Secodly please remove sudo, because for loading stuff from ftp to local pc you do not need root access! If you want to run script that you dowloaded, you need to add execute privilege to “update_blastdb.pl” file with this command “chmod u+x update_blastdb.pl” and run it with command:
    ./update_blastdb.pl –passive –timeout 300 –force –verbose nr

    Also one one more question. Is it possible to run blast with just nr.00 and nr.01 and not having whole database dowloaded? I tried tu run it, but I got error that he is missing nr.02. Is there a way to tell him that my database is just two nr arhives long?

    Thanks for sharing this blog and hoping to get reply soon.
