Constructor & Destructor Documentation

◆ FeatureFinderMultiplexAlgorithm()

default constructor

Member Function Documentation

◆ correctPeptideIntensities_()

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

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.

Parameters
intensity_peptidepeptide intensities to be corrected

◆ determinePeptideIntensitiesCentroided_()

std::vector<double> determinePeptideIntensitiesCentroided_ ( const MultiplexIsotopicPeakPattern pattern,
const std::multimap< size_t, MultiplexSatelliteCentroided > &  satellites

Parameters
pattern
satellites
Returns
vector with intensities for each of the peptides
