Detailed Description

Execute all steps in an OpenSwath analysis.

The workflow will perform a complete OpenSWATH analysis. Optionally, a calibration of m/z and retention time (mapping peptides to normalized space and correcting m/z error) can be performed beforehand using the OpenSwathCalibrationWorkflow class.

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

Obtain precursor ion chromatograms (if enabled) through MS1Extraction_()
Perform scoring of precursor ion chromatograms if no MS2 is given
Iterate through each SWATH-MS window:
- Select which transitions to extract (proceed in batches) using OpenSwathHelper::selectSwathTransitions()
- Iterate through each batch of transitions:
  - Extract current batch of transitions from current SWATH window:
    - Select transitions for current batch (see selectCompoundsForBatch_())
    - Prepare transition extraction (see prepareExtractionCoordinates_())
    - Extract transitions using ChromatogramExtractor::extractChromatograms()
    - Convert data to OpenMS format using ChromatogramExtractor::return_chromatogram()
  - Score extracted transitions (see scoreAllChromatograms_())
  - Write scored chromatograms and peak groups to disk (see writeOutFeaturesAndChroms_())

Constructor.

Parameters

use_ms1_traces	Whether to use MS1 data
use_ms1_ion_mobility	Whether to use ion mobility extraction on MS1 traces
threads_outer_loop	How many threads should be used for the outer loop (-1 will use all threads in the outer loop)

Helper function for selectCompoundsForBatch_()

Copy all transitions matching to one of the compounds in the selected peptide vector from all_transitions to the output.

Parameters

Execute OpenSWATH analysis on a set of SwathMaps and transitions.

See OpenSwathWorkflow class for a detailed description of this function.

Parameters

swath_maps	The raw data (swath maps)
rt_trafo	Retention time transformation description (translating this runs' RT to normalized RT space)
chromatogram_extraction_params	Parameter set for the chromatogram extraction
ms1_chromatogram_extraction_params	Parameter set for the chromatogram extraction of the MS1 data
feature_finder_param	Parameter set for the feature finding in chromatographic dimension
assay_library	The set of assays to be extracted and scored
result_featureFile	Output feature map to store identified features
store_features_in_featureFile	Whether features should be appended to the output feature map (if this is false, then out_featureFile will be empty)
result_tsv	TSV Writer object to store identified features in csv format (set store_features to false if using this option)
result_osw	OSW Writer object to store identified features in SQLite format (set store_features to false if using this option)
result_chromatograms	Chromatogram consumer object to store the extracted chromatograms
batchSize	Size of the batches which should be extracted and scored
int	ms1_isotopes Number of MS1 isotopes to extract (zero means only monoisotopic peak)
load_into_memory	Whether to cache the current SWATH map in memory

Note: Speed and memory performance can be influenced by batchSize and load_into_memory where larger batch sizes increase memory and potentially decrease the utility of parallelization while loading data into memory will increase memory usage but decrease execution time.

void scoreAllChromatograms_	(	const std::vector< OpenMS::MSChromatogram > &	ms2_chromatograms,

protected

Perform scoring on a set of chromatograms.

This will generate a new object of type MRMTransitionGroup for each compound or peptide in the provided assay library and link the transition meta information with the extracted chromatograms. This will then be used to perform peak picking and peak scoring through MRMTransitionGroupPicker and MRMFeatureFinderScoring. The assay library is provided as transition_exp and the chromatograms in ms2_chromatograms.

The overall execution flow is as follows:

Iterate over all assays (compounds / peptides) in the transition_exp
- Create a new MRMTransitionGroup
- Iterate over all transitions in an assay
  - Find the relevant chromatogram for the given transition, convert it and filter it by RT
  - Add the chromatogram and transition to the MRMTransitionGroup
- Add a single MS1 chromatogram of the mono-isotopic precursor to the MRMTransitionGroup, if available (named "groupId_Precursor_i0")
- Find peakgroups in the chromatogram set (see MRMTransitionGroupPicker::pickTransitionGroup)
- Score peakgroups in the chromatogram set (see MRMFeatureFinderScoring::scorePeakgroups)
- Add the identified peak groups to the TSV writer (tsv_writer) and the SQL-based output format (osw_writer)

Parameters

ms2_chromatograms	Input chromatograms (MS2 level)
ms1_chromatograms	Input chromatograms (MS1-level)
swath_maps	Set of swath map(s) for the current swath window (for SONAR multiple maps are provided)
transition_exp	The transition experiment (assay library)
feature_finder_param	Parameters for the MRMFeatureFinderScoring
trafo	RT Transformation function
rt_extraction_window	RT extraction window
output	Output map
tsv_writer	TSV writer for storing output (on the fly)
osw_writer	OSW Writer object to store identified features in SQLite format
ms1only	If true, will only score on MS1 level and ignore MS2 level

◆ selectCompoundsForBatch_()

void selectCompoundsForBatch_	(	const OpenSwath::LightTargetedExperiment &	transition_exp_used_all,
		OpenSwath::LightTargetedExperiment &	transition_exp_used,
		int	batch_size,
		size_t	batch_idx
	)

protected

Select which compounds to analyze in the next batch (and copy to output)

This function will select which compounds or peptides should be analyzed in the current batch (with index "batch_idx"). The selected compounds will be copied into the output structure. The output will contain "batch_size" compounds or peptides.

Parameters

transition_exp_used_all	The full set of transitions (this will be used to select transitions from)
transition_exp_used	The selected set of transitions (will contain only transitions for the next batch)
batch_size	How many compounds or peptides should be used per batch
batch_idx	Current batch index (only compounds or peptides from batch_idxbatch_size to batch_idxbatch_size+batch_size will be copied)

Note: The proteins will be copied completely without checking for a match

◆ writeOutFeaturesAndChroms_()

void writeOutFeaturesAndChroms_	(	std::vector< OpenMS::MSChromatogram > &	chromatograms,
		const FeatureMap &	featureFile,
		FeatureMap &	out_featureFile,
		bool	store_features,
		Interfaces::IMSDataConsumer *	chromConsumer
	)

protected

Write output features and chromatograms.

Writes output chromatograms to the provided chromatogram consumer (presumably to disk) and output features to the provided FeatureMap.

Parameters

chromatograms	Output chromatograms to be passed to the consumer
featureFile	Features to be appended to the output FeatureMap
out_featureFile	Output FeatureMap to which the features will be appended
store_features	Whether features should be appended to the output feature map (if this is false, then out_featureFile will be empty)
chromConsumer	Chromatogram consumer object to store the extracted chromatograms

Note: This should be wrapped in an OpenMP critical block
