Hi! I want to be able to use BLAST offline. I have already downloaded BLAST standalone file and unpacked everything. However, how do I download the entire protein database (BLASTP) to my local server (NAS)? And what is the easiest way to do this? wget? manual download? Or perhaps a BLAST command for this? I guess I also need to specify my database location after I've found a way to download it, as I am by the impression that it uses the "bin" folder per default.
Thanks!

NCBI makes this possible by providing a perl script that downloads the right data on your local desktop. More information is in this document. Make sure you have plenty of space and network bandwidth available (if you are working in a home office).
To download a preformatted NCBI BLAST database, run the update_blastdb.pl program followed by any relevant options and the name(s) of the BLAST databases to download. For example:
$ update_blastdb.pl --decompress nr [*]
