spectrum of a MALDI-TOF mass spectrometry measurement.

classes

A complete analysis pipeline for matrix-assisted laser
desorption/ionization-time-of-flight (MALDI-TOF) and other
two-dimensional mass spectrometry data. In addition to commonly
used plotting and processing methods it includes distinctive
features, namely baseline subtraction methods such as
morphological filters (TopHat) or the statistics-sensitive
non-linear iterative peak-clipping algorithm (SNIP), peak
alignment using warping functions, handling of replicated
measurements as well as allowing spectra with different
resolutions.
