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:

NameTypeDefaultRestrictionsDescription
filter:considered_hits int0 min: 0The number of top hits in each ID run that are considered for consensus scoring ('0' for all hits).
filter:min_support float0.0 min: 0.0 max: 1.0For 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 stringfalse true, falseCount empty ID runs (i.e. those containing no peptide hit for the current spectrum) when calculating 'min_support'?
filter:keep_old_scores stringfalse true, falseif set, keeps the original scores as user params

const std::map< String, String > &  se_info,
SequenceGrouping results 
)
overrideprivatevirtual

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
scoresList of scores for the same peptide by different search engines
higher_betterWhether higher or lower scores are better
Returns
Final score for the respective peptide

Implemented in ConsensusIDAlgorithmWorst, ConsensusIDAlgorithmRanks, ConsensusIDAlgorithmBest, and ConsensusIDAlgorithmAverage.

◆ operator=()

Not implemented.

◆ 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
idsInput/output peptide identifications
Exceptions
Exception::InvalidValueScore orientations do not agree

Reimplemented in ConsensusIDAlgorithmRanks.
