blast and update_blast.pl (nr files): No alias or index file found for protein database

Question

[paumarc]

Good morning

I recently download the nr files from ncbi ftp using the update_blastdb.pl script. When I try to run blast, i got an error telling I need a nr.pl file. I just tried to use makeblastdb to create the file using (makeblastdb -dbtype prot -out nr -title "non-redundant") but the script doesn't seem to work. can anyone tell me how to index those files or where to find the nr.pl document?

Could you copy / paste the exact update_blastdb and blast commands, and the error message? Did you uncompressed the database after downloading?
