Proteomics tools freely available at the Google Code !!

Most of the times researchers wonder as how to do a certain data analysis and then look for correct tool to get their work done. It might be some formula within MS Excel. When I get into that situation, I try to find the relevant tool at the Google Code.

Google code is a great place to find some of the open source tools and packages for various fields. I came across one such tool few months ago, PeptideShaker - It is useful to see search results from Mascot, OMSSA and X!Tandem. Other tools include Peptizer, Compomics,  dbtoolkit etc. Its always helpful to have some freely-available tools by your side.
