Detailed Description

This class is a metric for the QualityControl TOPP Tool.

This class counts the number of MissedCleavages per PeptideIdentification given a FeatureMap and returns an agglomeration statistic (observed counts). Additionally the PeptideHits in the FeatureMap are augmented with MetaInformation:

• 'missed_cleavages'
• 'FWHM' (from feature's 'FWHM' or 'model_FWHM')
• 'mass' (experimental mass of peptide)

Member Function Documentation

compute() [1/2]

void compute

(

FeatureMap &

fmap

)

Counts the number of missed cleavages per PeptideIdentification.

The result is a key/value map: #missed_cleavages –> counts Additionally the first PeptideHit in each PeptideIdentification of the FeatureMap is annotated with metavalue 'missed_cleavages'. The protease and digestion parameters are taken from the first ProteinIdentication (and SearchParameter therein) within the FeatureMap itself.

Parameters

fmap	FeatureMap with Peptide and ProteinIdentifications

compute() [2/2]

void compute	(	std::vector< ProteinIdentification > &	prot_ids,
		std::vector< PeptideIdentification > &	pep_ids
	)

get_missed_cleavages_from_peptide_identification_()

void get_missed_cleavages_from_peptide_identification_ ( const ProteaseDigestion &  digestor, MapU32 &  result, const UInt32 &  max_mc, PeptideIdentification &  pep_id  )

private

collects number of missed cleavages from PeptideIdentification in a result map (missed cleavages: occurences)

getName()

const String& getName ( ) const

overridevirtual

returns the name of the metric

Implements QCBase.

getResults()

const std::vector<std::map<UInt32, UInt32> >& getResults

(

)

const

returns the result as maps of number of missed_cleavages to counts; one map for each call to compute(...)

requirements()

QCBase::Status requirements ( ) const

overridevirtual

Returns the input data requirements of the compute(...) function.

Returns

Status for POSTFDRFEAT;
