ancient nr database

The download_lib.pl script still pulls down an nr database that is about three and a half years old. If one uses NCBI's update_blastdb.pl to get a modern copy, I-TASSER fails to work with it (run_I-TASSER.pl needs to be changed to check for ITLIB/nr/nr.pal instead of ITLIB/nr/nr according to what I found in the forum archives). Is this a problem, or does the blast database not matter much for I-TASSER?

I would have expected that download_lib.pl would internally call update_blastdb.pl as part of getting the nr database, unless you have some curated modifications to it.
