Detailed Description

QC metric calculating (un)calibrated m/z error.

The metric sets m/z-values of the original experiment and the calculated reference m/z-values, uncalibrated m/z error (ppm) and calibrated m/z error (ppm) as metavalues of all PeptideIdentifications in a FeatureMap.

For full functionality a PeakMap/MSExperiment with original m/z-values before m/z calibration generated by InternalCalibration has to be given. It's also possible to use this without an MzML File, but then only uncalibrated m/z error (ppm) will be reported. A FeatureMap after FDR is always required.

Member Function Documentation

addMzMetaValues_()

void addMzMetaValues_ ( PeptideIdentification &  peptide_ID, const MSExperiment &  exp, const QCBase::SpectraMap &  map_to_spectrum  )

private

calculate the m/z values and m/z errors and add them to the PeptideIdentification

compute()

void compute	(	FeatureMap &	features,
		const MSExperiment &	exp,
		const QCBase::SpectraMap &	map_to_spectrum
	)

Writes results as meta values to the PeptideIdentification of the given FeatureMap.

Parameters

features	FeatureMap with m/z-values of PeptideIdentification after calibration, meta values are added here
exp	PeakMap of the original experiment. Can be empty (i.e. not available).
map_to_spectrum	Map to find index of spectrum given by meta value at PepID

Exceptions

Exception::InvalidParameter	PeptideID is missing meta value 'spectrum_reference'
Exception::IllegalArgument	Spectrum for a PepID has MSLevel of 1
Exception::MissingInformation	Meta value 'mz_raw' missing from MSExperiment
