## 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.
