In MassSpecWavelet: Mass spectrum processing by wavelet-based algorithms

Description

Process Mass Spectrum (MS) by Wavelet Transforms-based algorithms

Details

Package:	MassSpecWavelet
Type:	Package
Version:	1.0.4
Date:	2007-04-05
License:	GPL 2 or newer

MassSpecWavelet R package is aimed to process Mass Spectrometry (MS) data mainly based on Wavelet Transforms. The current version only supports the peak detection based on Continuous Wavelet Transform (CWT). Future versions will include more functions covering entire MS data processes.

Examples

data(exampleMS)
SNR.Th <- 3
peakInfo <- peakDetectionCWT(exampleMS, SNR.Th=SNR.Th)
majorPeakInfo = peakInfo$majorPeakInfo
peakIndex <- majorPeakInfo$peakIndex
plotPeak(exampleMS, peakIndex, main=paste('Identified peaks with SNR >', SNR.Th))
