mMass - Open Source Mass Spectrometry Tool

mMass presents open source multi-platform package of tools for precise mass spectrometric data analysis and interpretation. It is written in Python language and released under GNU General Public License, so it’s portable to different computer platforms and has a good potential to be easily modified or extended by modules of specific needs.
