Constructor & Destructor Documentation

OpenSwathWorkflowBase() [1/2]

OpenSwathWorkflowBase ( )

inlineprotected

Default constructor.

Will not use any ms1 traces and use all threads in the outer loop.

OpenSwathWorkflowBase() [2/2]

OpenSwathWorkflowBase ( bool  use_ms1_traces, bool  use_ms1_ion_mobility, bool  prm, bool  pasef, int  threads_outer_loop  )

inlineprotected

Constructor.

Parameters

use_ms1_traces	Use MS1 data?
use_ms1_ion_mobility	Use ion mobility extraction on MS1 traces?
prm	Is data acquired in targeted DIA (e.g. PRM mode) with potentially overlapping windows?
pasef	Is this diaPASEF data?
threads_outer_loop	How many threads should be used for the outer loop (-1 will use all threads in the outer loop)

Note

The total number of threads should be divisible by this number (e.g. use 8 in outer loop if you have 24 threads in total and 3 will be used for the inner loop).

Member Function Documentation

MS1Extraction_()

void MS1Extraction_ ( const OpenSwath::SpectrumAccessPtr &  ms1_map, const std::vector< OpenSwath::SwathMap > &  swath_maps, std::vector< MSChromatogram > &  ms1_chromatograms, const ChromExtractParams &  cp, const OpenSwath::LightTargetedExperiment &  transition_exp, const TransformationDescription &  trafo_inverse, bool  ms1_only = false, int  ms1_isotopes = 0  )

protected

Perform MS1 extraction and store result in ms1_chromatograms.

Parameters

ms1_map	Spectrum Access to the MS1 map
swath_maps	The raw data (swath maps)
ms1_chromatograms	Output vector for MS1 chromatograms
cp	Parameter set for the chromatogram extraction
transition_exp	The set of assays to be extracted and scored
trafo_inverse	Inverse transformation function
ms1_only	If true, will only score on MS1 level and ignore MS2 level
ms1_isotopes	Number of MS1 isotopes to extract (zero means only monoisotopic peak)

prepareExtractionCoordinates_()

void prepareExtractionCoordinates_ ( std::vector< OpenSwath::ChromatogramPtr > &  chrom_list, std::vector< ChromatogramExtractorAlgorithm::ExtractionCoordinates > &  coordinates, const OpenSwath::LightTargetedExperiment &  transition_exp_used, const TransformationDescription &  trafo_inverse, const ChromExtractParams &  cp, const bool  ms1 = false, const int  ms1_isotopes = -1  ) const

protected

Function to prepare extraction coordinates that also correctly handles RT transformations.

Creates a set of (empty) chromatograms and extraction coordinates with the correct ids, m/z and retention time start/end points to be extracted by the ChromatogramExtractor.

Handles RT extraction windows by calculating the correct transformation for each coordinate.

Parameters

chrom_list	Output of chromatograms (will be filled with empty chromatogram ptrs)
coordinates	Output of extraction coordinates (will be filled with matching extraction coordinates)
transition_exp_used	The transition experiment used to create the coordinates
trafo_inverse	Inverse transformation function
cp	Parameter set for the chromatogram extraction
ms1	Whether to perform MS1 (precursor ion) or MS2 (fragment ion) extraction
ms1_isotopes	Number of MS1 isotopes to extract (zero means only monoisotopic peak)

Member Data Documentation

ms1_map_

OpenSwath::SpectrumAccessPtr ms1_map_ = nullptr

protected

Spectrum Access to the MS1 map (note that this is not threadsafe!)

Note

This pointer is not threadsafe, please use the lightClone() function to create a copy for each thread

This pointer may be NULL if use_ms1_traces_ is set to false

pasef_

bool pasef_

protected

Whether data is diaPASEF data.

If set to true, a precursor will only be extracted from a single window that matches both in m/z and whose ion mobility (drift time) center is closest to the library ion mobility of the precursor. This is required if windows overlap in m/z or in ion mobility, as is the case for diaPASEF data.

prm_

bool prm_

protected

Whether data is acquired in targeted DIA (e.g. PRM mode) with potentially overlapping windows.

If set to true, a precursor will only be extracted from a single window that matches in m/z and whose m/z center is closest to the library m/z of the precursor. This is required if windows overlap in m/z as is the case for SRM / PRM data where often multiple windows with similar (or overlaping) m/z are used to target different precursors at different RT.

threads_outer_loop_

int threads_outer_loop_

protected

How many threads should be used for the outer loop.

Note

A value of -1 will use all threads in the outer loop

The total number of threads should be divisible by this number (e.g. use 8 in outer loop if you have 24 threads in total and 3 will be used for the inner loop).

use_ms1_ion_mobility_

bool use_ms1_ion_mobility_

protected

Whether to use ion mobility extraction on MS1 traces.

use_ms1_traces_

bool use_ms1_traces_

protected

Whether to use the MS1 traces.
