[Bioperl-l] how to rename genbank header in fasta file?

[Jason Stajich]

> perl -i -p -e 's/>.+\[gene=([^\]]+)\].+/>$1/' file.fa

should have been -e not -s in my example.

you can name the file whatever you want just replace that part in the command above-- it sounds like you are really new to Perl in general so I would recommend some basic books first if you are this new to programming and running scripts - try Unix and Perl to the Rescue at http://unixandperl.com
