Thank you, including Duleep and David Lapointe for the prompt responses and for describing it in complete detail. I got what I couldn't find going through REBASE website and looking into EMBOSS' web pages. Excuse me for my ignorance, where can I find a manual or a good documentation on the EMBOSS package.

Go to the /pub/rebase dir on ftp.neb.com.
Download the withrefm.xxx and proto.xxx files
(xxx stands for the version number, just take the latest that's there)
Run rebaseextract -infile withrefm.xxx -protofile proto.xxx
This reformats the neb files for use with emboss. You should now see
4 files embossre.... in the REBASE directory

I'm not sure about the whole genome but I have used it for individual
chromosomes without problems.

You can run restrict with the option -fragments to get them.
Hope this helps,
