Detailed Description

Execute all steps for retention time and m/z calibration of SWATH-MS data.

Uses a set of robust calibrant peptides (e.g. iRT peptides, common calibrants) perform RT and m/z correction in SWATH-MS data. Currently supports (non-)linear correction of RT against library RT as well as (non-)linear correction of m/z error as a function of m/z.

Note: The relevant algorithms are implemented in MRMRTNormalizer for RT calibration and SwathMapMassCorrection for m/z calibration.

The overall execution flow in this class is as follows (see performRTNormalization() function):

Extract chromatograms across the whole RT range using simpleExtractChromatograms_()
Compute calibration functions for RT and m/z using doDataNormalization_()

◆ addChromatograms()

static void addChromatograms	(	MSChromatogram &	base_chrom,
		const MSChromatogram &	newchrom
	)

static

Add two chromatograms.

Parameters

base_chrom	The base chromatogram to which we will add intensity
newchrom	The chromatogram to be added

◆ doDataNormalization_()

TransformationDescription doDataNormalization_	(	const OpenSwath::LightTargetedExperiment &	transition_exp_,
		const std::vector< OpenMS::MSChromatogram > &	chromatograms,
		TransformationDescription &	im_trafo,
		std::vector< OpenSwath::SwathMap > &	swath_maps,
		double	min_rsq,
		double	min_coverage,
		const Param &	default_ffparam,
		const Param &	irt_detection_param,
		const Param &	calibration_param
	)

Perform retention time and m/z calibration.

Uses MRMRTNormalizer for RT calibration and SwathMapMassCorrection for m/z calibration.

The overall execution flow is as follows:

Estimate the retention time range of the iRT peptides over all assays (see OpenSwathHelper::estimateRTRange())
Store the peptide retention times in an intermediate map
Pick input chromatograms to identify RT pairs from the input data using MRMFeatureFinderScoring, which will be used without the RT scoring enabled
Find most likely correct feature for each compound (see OpenSwathHelper::simpleFindBestFeature())
Perform the outlier detection (see MRMRTNormalizer)
Check whether the found peptides fulfill the binned coverage criteria set by the user.
Select the "correct" peaks for m/z correction (e.g. remove those not part of the linear regression)
Perform m/z calibration (see SwathMapMassCorrection)
Store transformation, using the selected model

Parameters

transition_exp_	The transitions for the normalization peptides
chromatograms	The extracted chromatograms
min_rsq	Minimal R^2 value that is expected for the RT regression
min_coverage	Minimal coverage of the chromatographic space that needs to be achieved
default_ffparam	Parameter set for the feature finding in chromatographic dimension
irt_detection_param	Parameter set for the detection of the iRTs (outlier detection, peptides per bin etc)
calibration_param	Parameter for the m/z and im calibration (see SwathMapMassCorrection)

Note: This function is based on the algorithm inside the OpenSwathRTNormalizer tool

◆ performRTNormalization()

TransformationDescription performRTNormalization	(	const OpenSwath::LightTargetedExperiment &	irt_transitions,
		std::vector< OpenSwath::SwathMap > &	swath_maps,
		TransformationDescription &	im_trafo,
		double	min_rsq,
		double	min_coverage,
		const Param &	feature_finder_param,
		const ChromExtractParams &	cp_irt,
		const Param &	irt_detection_param,
		const Param &	calibration_param,
		const String &	irt_mzml_out,
		Size	debug_level,
		bool	sonar = `false`,
		bool	load_into_memory = `false`
	)

Perform RT and m/z correction of the input data using RT-normalization peptides.

This function extracts the RT normalization chromatograms using simpleExtractChromatograms_() and then uses the chromatograms to find features (in doDataNormalization_()). If desired, also m/z correction is performed using the lock masses of the given peptides. The provided raw data (swath_maps) are therefore not constant but may be changed in this function.

Parameters

irt_transitions	A set of transitions used for the RT normalization peptides
swath_maps	The raw data (swath maps)
min_rsq	Minimal R^2 value that is expected for the RT regression
min_coverage	Minimal coverage of the chromatographic space that needs to be achieved
feature_finder_param	Parameter set for the feature finding in chromatographic dimension
cp_irt	Parameter set for the chromatogram extraction
irt_detection_param	Parameter set for the detection of the iRTs (outlier detection, peptides per bin etc)
calibration_param	Parameter for the m/z and im calibration (see SwathMapMassCorrection)
debug_level	Debug level (writes out the RT normalization chromatograms if larger than 1)
irt_mzml_out	Output Chromatogram mzML containing the iRT peptides (if not empty, iRT chromatograms will be stored in this file)
sonar	Whether the data is SONAR data
load_into_memory	Whether to cache the current SWATH map in memory
