msms

Two tandem mass spec meassured on a linear ion trap coupled to an Orbitrap 
 mass analyzer (Thermo Scientific, Bremen, Germany). The protein sample originates from 10 mouse brain homogenate, prepared in sterile PBS containing protease
 inhibitors (Complete; Riche, Switzerland) by repeated extrusion through
 syringe needles of successive smaller size. To remove gross cellular
 debris the homogenate was centrifuged for 10 min at 2400 rpm
 at 4 degrees centigrade. The data were acquired withing the Sixth Framework Programm (FP6-37457). The project was called SysProt.

datasets

This R package helps with quality checks, vizualizations
        and analysis of mass spectrometry data, coming from proteomics
        experiments. The package is developed, tested and used at the
        Functional Genomics Center Zurich. We use this package mainly
        for prototyping, teaching, and having fun with proteomics data.
        But it can also be used to do solid data analysis for small
        scale data sets.

msms: A data set containing tandem mass spectra of an LCMS experiment.
