Detailed Description

Performs a Bayesian protein inference on Protein/Peptide identifications or ConsensusMap (experimental).

Constructor & Destructor Documentation

◆ BayesianProteinInferenceAlgorithm()

BayesianProteinInferenceAlgorithm ( unsigned int  debug_lvl = 0)
explicit

Constructor.

Todo:
is there a better way to pass the debug level from TOPPBase?

◆ ~BayesianProteinInferenceAlgorithm()

~BayesianProteinInferenceAlgorithm ( )
overridedefault

Destructor.

Member Function Documentation

◆ inferPosteriorProbabilities() [1/2]

void inferPosteriorProbabilities ( ConsensusMap cmap,
boost::optional< const ExperimentalDesign exp_des = boost::optional< const ExperimentalDesign >() 
)

Perform inference. Filter, build graph, run the private inferPosteriorProbabilities_ function. Writes its results into protein and (optionally also) peptide hits (as new score). Optionally adds indistinguishable protein groups with separate scores, too. See Param object of class. Loops over all runs in the ConsensusMaps' protein IDs. (experimental)

◆ inferPosteriorProbabilities() [2/2]

void inferPosteriorProbabilities ( std::vector< ProteinIdentification > &  proteinIDs,
std::vector< PeptideIdentification > &  peptideIDs,
boost::optional< const ExperimentalDesign exp_des = boost::optional< const ExperimentalDesign >() 
)

Perform inference. Filter, build graph, run the private inferPosteriorProbabilities_ function. Writes its results into protein and (optionally also) peptide hits (as new score). Optionally adds indistinguishable protein groups with separate scores, too. See Param object of class. Currently only takes first proteinID run and all peptides. Experimental design can be used to create an extended graph with replicate information. (experimental) @TODO loop over all runs

◆ inferPosteriorProbabilities_()

void inferPosteriorProbabilities_ ( Internal::IDBoostGraph ibg)
private

after a graph was built, use this method to perform inference and write results to the structures with which the graph was built

◆ initGridSearchFromParams_()

GridSearch<double,double,double> initGridSearchFromParams_ ( std::vector< double > &  alpha_search,
std::vector< double > &  beta_search,
std::vector< double > &  gamma_search 
)
private

read Param object and set the grid

◆ setScoreTypeAndSettings_()

void setScoreTypeAndSettings_ ( ProteinIdentification proteinIDs)
private

set score type and settings for every ProteinID run processed

◆ updateMembers_()

void updateMembers_ ( )
overridevirtual

This method is used to update extra member variables at the end of the setParameters() method.

Also call it at the end of the derived classes' copy constructor and assignment operator.

The default implementation is empty.

Reimplemented from DefaultParamHandler.

Member Data Documentation

◆ checkConvertAndFilterPepHits_

std::function<void(PeptideIdentification&)> checkConvertAndFilterPepHits_
private

function initialized based on the algorithm parameters that is used to filter PeptideHits

Todo:
extend to allow filtering only for the current run

◆ debug_lvl_

unsigned int debug_lvl_
private
