Hi Peter,

This is what I get:

[auerbach@babar ~]$ ls /9720/genome_references/ncbi/nr-protein-db/nr-newstyle/nr*

/9720/genome_references/ncbi/nr-protein-db/nr-newstyle/nr

/9720/genome_references/ncbi/nr-protein-db/nr-newstyle/nr.gz

Normally you would download and decompress all of the NR database from the NCBI FTP site. It is currently in seven parts (seven tar balls), available here: ftp://ftp.ncbi.nlm.nih.gov/blast/db/

Where did your nr.gz file come from? That isn't normal... but perhaps it was copied from another server - what is inside it?
