To get a total combined Fasta file from nr.gz file

Question

[dpktiwari168]

Hello,

I am trying to get a combined Fasta file for all the sequences that are present in the nr database. For that I have downloaded the nr database from ftp://ftp.ncbi.nlm.nih.gov/blast/db/FASTA/nr.gz.

I have unzipped the nr.gz file and then I have got a single nr file which is a binary file of 131.9 GB. I want to have all these files as a fasta File (.fasta file). How can I get that? Please suggest.

Thanks

if you unzip that file you should get a plain text (=FASTA ) file.

what program did you use to 'unzip' that file? (== you should use gzip )
