Detailed Description

Abstract base class for ConsensusID algorithms that compare only identical sequences.

Search engine scores are grouped by peptide sequence in apply_(). For each sequence, getAggregateScore_() is called to produce a consensus score from the list of search engine scores.

All derived classes should implement getAggregateScore_(). They may re-implement preprocess_() if required.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
filter:considered_hits	int	0	min: 0	The number of top hits in each ID run that are considered for consensus scoring ('0' for all hits).
filter:min_support	float	0	min: 0 max: 1	For each peptide hit from an ID run, the fraction of other ID runs that must support that hit (otherwise it is removed).
filter:count_empty	string	false	true, false	Count empty ID runs (i.e. those containing no peptide hit for the current spectrum) when calculating 'min_support'?

Member Function Documentation

◆ apply_()

virtual void apply_	(	std::vector< PeptideIdentification > &	ids,
		SequenceGrouping &	results
	)

Consensus scoring.

Implements ConsensusIDAlgorithm.

◆ getAggregateScore_()

virtual double getAggregateScore_	(	std::vector< double > &	scores,
		bool	higher_better
	)

protectedpure virtual

Aggregate peptide scores into one final score (to be implemented by subclasses).

Parameters

scores	List of scores for the same peptide by different search engines
higher_better	Whether higher or lower scores are better

Returns: Final score for the respective peptide

Implemented in ConsensusIDAlgorithmRanks, ConsensusIDAlgorithmAverage, ConsensusIDAlgorithmBest, and ConsensusIDAlgorithmWorst.

◆ preprocess_()

virtual void preprocess_ ( std::vector< PeptideIdentification > & ids )

protectedvirtual

Preprocessing of peptide IDs (in the beginning of "apply_").

Checks whether the score types are the same (warns if not) and whether the score orientations agree (error if not).

Parameters

ids	Input/output peptide identifications

Exceptions

Exception::InvalidValue Score orientations do not agree

Reimplemented in ConsensusIDAlgorithmRanks.
