ProteomeCommons.org Java Analysis Framework is a framework for referencing common mass spectrometry data such as atoms and residues. This framework provides a programmer with an easy-to-use library for writing programs that rely on common mass spectrometry data. The framework also contains utilities such as an isotope calculator and a reference for residue abbreviations.
ProteomeCommons.org IO Framework is a proper Java framework for handling spectra and peak lists. The framework can read and write to a number of different spectra and peak list formats, and it provides a simple, intuitive Java object model for working with spectra or peak lists. All classes support two methods of handling peak list and spectrum data: in-memory or stream. The goal of this framework is to support all the popular MS and MSMS data formats, and to eliminate any time or effort involved in figuring out how to read and write peak list or spectrum files.
