seq_format-converter

A script to convert a sequence file to another format.

Synopsis

perl seq_format-converter.pl -i seq_file.gbk -f gbk -o embl

Description

This script converts a (multi-)sequence file of a specific format to a differently formatted output file. The most common sequence formats are: embl, fasta, and gbk (genbank).

Since sequence formats change from time to time, BioPerl is not always up to date. For all available BioPerl sequence formats see: http://www.bioperl.org/wiki/HOWTO:SeqIO#Formats. Warning: The bioperl-ext package and the io_lib library from the Staden package (http://staden.sourceforge.net/) need to be installed in order to read the scf, abi, alf, pln, exp, ctf, ztr formats.

Usage

perl seq_format-converter.pl -i seq_file -f in_format -o out_format

UNIX loop to reformat all sequence files in the current working directory

for i in *.[embl|gbk]; do perl seq_format-converter.pl -i $i -f [embl|gbk] -o [embl|fasta|gbk]; done
