BLAST error: Input db vol size does not match lmdb vol size

Question

[Hansen_869]

When trying to run blastp (stand-alone) with the NR database (I downloaded all 42 nr files and unzipped them onto my NAS).

When running the line:

blastp -query C:\Users\Myuser\Desktop\Fastas\Myfasta.fasta -db Y:\NAS_Server\BLAST\NR -out result.txt -outfmt 6 -evalue 0.00001 -max_target_seqs 1

I receive the following error: Input db vol size does not match lmdb vol size

Any suggestions?

Did you download ALL nr* files (there are 41 as of today) from NCBI and uncompress them? All nr* files need to be in the same folder.

Also read about -max_target_seq option. That does not guarantee that you will get the best/top hit.
