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").
