[Bioperl-l] formatdb with the nr database

[Hubert Prielinger]

Hi,
I have downloaded the nr database for doing a blast search locally, now 
I'm supposed to index the database with formatdb, but it doesn't work...
The online help says that you need a fasta file that is indexed to use 
for searching the database, but when I uncompressed the zip file, there 
were only .phr, .pnd, .pin, .pni, .ppd file....
Is there anybody who can tell me, how to use formatdb with the nr 
database...

Help is very appreciated
Thank you very much in advance

Hubert
