Constructor & Destructor Documentation

ConfidenceScoring()

ConfidenceScoring ( bool  test_mode_ = false )

explicit

Constructor.

~ConfidenceScoring()

~ConfidenceScoring ( )

inlineoverride

Member Function Documentation

chooseDecoys_()

void chooseDecoys_ ( )

protected

Randomize the list of decoy indexes.

getAssayRT_()

double getAssayRT_ ( const TargetedExperiment::Peptide &  assay )

protected

Get the retention time of an assay.

initialize()

void initialize ( const TargetedExperiment &  library, const Size  n_decoys, const Size  n_transitions, const TransformationDescription &  rt_trafo  )

inline

initializeGlm()

void initializeGlm ( double  intercept, double  rt_coef, double  int_coef  )

inline

manhattanDist_()

double manhattanDist_ ( DoubleList  x, DoubleList  y  )

protected

Manhattan distance.

scoreAssay_()

double scoreAssay_ ( const TargetedExperiment::Peptide &  assay, double  feature_rt, DoubleList &  feature_intensities, const std::set< String > &  transition_ids = std::set< String >()  )

protected

Score the assay assay against feature data (feature_rt, feature_intensities), optionally using only the specified transitions (transition_ids)

scoreFeature_()

void scoreFeature_ ( Feature &  feature )

protected

Score a feature.

scoreMap()

void scoreMap ( FeatureMap &  features )

inline

Score a feature map -> make sure the class is properly initialized.

both functions initializeGlm and initialize need to be called first.

The input to the program is

• a transition library which contains peptides with corresponding assays.
• a feature map where each feature corresponds to an assay (mapped with MetaValue "PeptideRef") and each feature has as many subordinates as the assay has transitions (mapped with MetaValue "native_id").
