◆ correctPeptideIntensities_()

void correctPeptideIntensities_	(	const MultiplexIsotopicPeakPattern &	pattern,
		std::map< size_t, SplinePackage > &	spline_chromatograms,
		const std::vector< double > &	rt_peptide,
		std::vector< double > &	intensity_peptide
	)		const

determine ratios through linear regression and correct peptide intensities

In most labelled mass spectrometry experiments, the fold change i.e. ratio and not the individual peptide intensities are of primary interest. For that reason, we determine the ratios from interpolated chromatogram data points directly, and then correct the current ones.
