toyspectrum: Simulated protein mass spectrum

In IPPD: Isotopic peak pattern deconvolution for Protein Mass Spectrometry by template matching

Description

A simulated dataset for testing purposes. m/z ranges from 800 to about 4000 Thomson, sampled at approximately 118,000 points. The isotopic patterns present in this artificial dataset exactly obey the Averagine model in combination with Exponentially Modified Gaussians peak shapes, s. fitModelParameters if no noise were present. The noise has been generated from two sources: the first is a baseline pattern of Gaussian bumps with low intensity and the second one is additive noise drawn from a truncated Gaussian distribution. The dataset contains about 300, partially heavily overlapping, peak patterns whose data are stored in data(toyspectrumsolution).
