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):

Parameters
base_chromThe base chromatogram to which we will add intensity
newchromThe chromatogram to be added

◆ doDataNormalization_()

TransformationDescription doDataNormalization_ ( const OpenSwath::LightTargetedExperiment transition_exp_,
const std::vector< OpenMS::MSChromatogram > &  chromatograms,

double  min_rsq,

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
chromatogramsThe extracted chromatograms
min_rsqMinimal R^2 value that is expected for the RT regression
min_coverageMinimal coverage of the chromatographic space that needs to be achieved
default_ffparamParameter set for the feature finding in chromatographic dimension
irt_detection_paramParameter set for the detection of the iRTs (outlier detection, peptides per bin etc)
calibration_paramParameter 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_transitionsA set of transitions used for the RT normalization peptides
swath_mapsThe raw data (swath maps)
min_rsqMinimal R^2 value that is expected for the RT regression
min_coverageMinimal coverage of the chromatographic space that needs to be achieved
feature_finder_paramParameter set for the feature finding in chromatographic dimension
cp_irtParameter set for the chromatogram extraction
irt_detection_paramParameter set for the detection of the iRTs (outlier detection, peptides per bin etc)
calibration_paramParameter for the m/z and im calibration (see SwathMapMassCorrection)
debug_levelDebug level (writes out the RT normalization chromatograms if larger than 1)
irt_mzml_outOutput Chromatogram mzML containing the iRT peptides (if not empty, iRT chromatograms will be stored in this file)
sonarWhether the data is SONAR data
load_into_memoryWhether to cache the current SWATH map in memory
