I have downloaded the preformatted nr db using the below command and uncompressed all files to a folder. The folder contains multiple files such as nr.pto, nr.pot, nr.38.pog etc.
Executing the following command says blastp -query file.fasta -db nr -out results.out BLAST Database error: No alias or index file found for protein database [nr] in search path.
I tried doing makeblastdb -dbtype prot -in nr and it deleted all the files in my nr folder.
Is this the right step before executing a blastp?
