VI: format your custom database by replace function

Couple days ago, I used nucleotide seqs from JGI website and had to create my own blast database. Before I do that, I had to get rid of some of the extra defline info that makes sense only for JGI. I did it with VIM editor

Usage:

%s/search_pattern/replace_pattern/g

Example:

%s/jgi|Poptr1_1|[0-9]*//g

Enjoy!
