msmsR Documentation

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

Description

The purpose of msms is for the demonstration of the peptide identification methods, e.g., peakplot or psm.

msms contains two tandem mass spectra 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.
