Member Function Documentation

chargeTestworthy_()

bool chargeTestworthy_ ( const Int  feature_charge, const Int  putative_charge, const bool  other_unchanged  ) const

protected

determines if we should test a putative feature charge

Answer query given the internal status of q_try. Features with q<=0 always return true.

checkSolution_()

void checkSolution_ ( const ConsensusMap &  cons_map ) const

protected

compute()

void compute	(	const FeatureMapType &	fm_in,
		FeatureMapType &	fm_out,
		ConsensusMap &	cons_map,
		ConsensusMap &	cons_map_p
	)

Compute a zero-charge feature map from a set of charged features.

Find putative ChargePairs, then score them and hand over to ILP.

Parameters

fm_in	Input feature-map
fm_out	Output feature-map (sorted by position and augmented with user params)
cons_map	[out] Output of grouped features belonging to a charge group
cons_map_p	[out] Output of paired features connected by an edge

inferMoreEdges_()

void inferMoreEdges_ ( PairsType &  edges, Map< Size, std::set< CmpInfo_ > > &  feature_adducts  )

protected

test if "simple" edges have alternative (more difficult explanation) supported by neighboring edges e.g. (.) -> (H+) might be augmented to (Na+) -> (H+Na+)

intensityFilterPassed_()

bool intensityFilterPassed_ ( const Int  q1, const Int  q2, const Compomer &  cmp, const FeatureType &  f1, const FeatureType &  f2  )

inlineprotected

returns true if the intensity filter was passed or switched off

Filter for adding an edge only when the two features connected by it, fulfill the intensity criterion.

operator=()

MetaboliteFeatureDeconvolution& operator=

(

const MetaboliteFeatureDeconvolution &

source

)

Assignment operator.

printEdgesOfConnectedFeatures_()

void printEdgesOfConnectedFeatures_ ( Size  idx_1, Size  idx_2, const PairsType &  feature_relation  )

protected

A function mostly for debugging.

updateMembers_()

void updateMembers_ ( )

protectedvirtual

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.
