◆ annotatePSMExplainedIonCurrent_()

static double annotatePSMExplainedIonCurrent_	(	PeptideIdentification &	pep_id,
		const MSExperiment &	exp,
		const QCBase::SpectraMap &	map_to_spectrum,
		WindowMower &	filter,
		PSMExplainedIonCurrent::ToleranceUnit	tolerance_unit,

◆ compute() [1/2]

void compute	(	FeatureMap &	fmap,
		const MSExperiment &	exp,
		const QCBase::SpectraMap &	map_to_spectrum,
		ToleranceUnit	tolerance_unit = `ToleranceUnit::AUTO`,
		double	tolerance = `20`
	)

computes PSMExplainedIonCurrent (only of the first PeptideHit of each PepID)

To calculate PSMExplainedIonCurrent the theoretical spectrum is generated and matched with the original one. After that: PSMExplainedIonCurrent = sum of matched peaks intensity / total intensity

Stores average and variance of PSMExplainedIonCurrent as a struct and stores it in the results vector (can be accessed by getResults()). Each PSMExplainedIonCurrent is also stored in the first PeptideHit of the corresponding PeptideIdentification as metavalue "PSM_correctness".

Parameters

fmap	Input FeatureMap for annotation and data for theoretical spectra
exp	Input MSExperiment for MS2 spectra; spectra should be sorted (ascending RT)
map_to_spectrum	Map to find index of spectrum given by meta value at PepID
tolerance	Search window for matching peaks; distance has to be lower than tolerance value
tolerance_unit	Tolerance in ppm or Dalton (if auto was chosen, the unit and value will taken from FeatureMap metadata)

Exceptions

Exceptions::MissingInformation	If fragment mass tolerance is missing in metadata of FeatureMap (& no ToleranceUnit is given)
Exception::InvalidParameter	PeptideID is missing meta value 'spectrum_reference'
Exception::IllegalArgument	Spectrum for a PepID has ms-level of 1
Exception::MissingInformation	If PSMExplainedIonCurrent couldn't be calculated for any spectrum. (i.e. all spectra are: empty, contain only peaks with intensity 0 or the matching pep_id has no hits)
Exception::InvalidParameter	If the fragmentation method is not ECD, ETD, CID or HCD

◆ compute() [2/2]

void compute	(	std::vector< PeptideIdentification > &	pep_ids,
		const ProteinIdentification::SearchParameters &	search_params,
		const MSExperiment &	exp,
		const QCBase::SpectraMap &	map_to_spectrum,
		ToleranceUnit	tolerance_unit = `ToleranceUnit::AUTO`,
		double	tolerance = `20`
	)

computes PSMExplainedIonCurrent (only of the first PeptideHit of each PepID)

Same as above, but with PeptideIdentification + SearchParameter input instead of FeatureMap

Parameters

pep_ids	Input peptide identifications for annotation and data for theoretical spectra
search_params	Input search parameters from ID-search that generated the peptide identifications from `pep_ids`
exp	Input MSExperiment for MS2 spectra; spectra should be sorted (ascending RT)
map_to_spectrum	Map to find index of spectrum given by meta value at PepID
tolerance	Search window for matching peaks; distance has to be lower than tolerance value
tolerance_unit	Tolerance in ppm or Dalton (if auto was chosen, the unit and value will taken from FeatureMap metadata)

Exceptions

Exceptions::MissingInformation	If fragment mass tolerance is missing in metadata of FeatureMap (& no ToleranceUnit is given)
Exception::InvalidParameter	PeptideID is missing meta value 'spectrum_reference'
Exception::IllegalArgument	Spectrum for a PepID has ms-level of 1
Exception::MissingInformation	If PSMExplainedIonCurrent couldn't be calculated for any spectrum. (i.e. all spectra are: empty, contain only peaks with intensity 0 or the matching pep_id has no hits)
Exception::InvalidParameter	If the fragmentation method is not ECD, ETD, CID or HCD
