Good morning

I recently download the nr files from ncbi ftp using the script. When I try to run blast, i got an error telling I need a 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 document?
