Detailed Description

File adapter for Swath files.

This class can load SWATH files in different storage versions. The most convenient file is a single MzML file which contains one experiment. However, also the loading of a list of files is supported (loadSplit) where it is assumed that each individual file only contains scans from one precursor isolation window (one SWATH). Finally, experimental support for mzXML is available but needs to be selected with a specific compile flag (this is not for everyday use).

Member Function Documentation

◆ countScansInSwath_()

void countScansInSwath_	(	const std::vector< MSSpectrum > &	exp,
		std::vector< int > &	swath_counter,
		int &	nr_ms1_spectra,
		std::vector< OpenSwath::SwathMap > &	known_window_boundaries,
		double	TOLERANCE = `1e-6`
	)

protected

Counts the number of scans in a full Swath file (e.g. concatenated non-split file)

◆ doCacheFile_()

OpenSwath::SpectrumAccessPtr doCacheFile_	(	const std::string &	in,
		const std::string &	tmp,
		const std::string &	tmp_fname,
		const std::shared_ptr< PeakMap > &	experiment_metadata
	)

protected

Cache a file to disk.

◆ loadFromMSExperiment()

std::vector< OpenSwath::SwathMap > loadFromMSExperiment	(	const std::shared_ptr< PeakMap > &	exp,
		const std::string &	tmp,
		std::shared_ptr< ExperimentalSettings > &	exp_meta,
		const std::string &	readoptions = `"normal"`
	)

Loads a Swath run from a pre-loaded in-memory MSExperiment.

Used when the input format does not have a streaming reader (e.g. Thermo .raw via openms-thermo-bridge), so the full experiment has already been materialized. Avoids the round-trip through a temporary mzML file.

Parameters

[in]	exp	The pre-loaded experiment (must contain all spectra and metadata)
[in]	tmp	Temporary directory (used only for readoptions=="cache")
[out]	exp_meta	ExperimentalSettings extracted from `exp`
[in]	readoptions	"normal" (in-memory) or "cache" (disk-cached)

Returns: Swath maps for MS2 and MS1

◆ loadMzML()

std::vector< OpenSwath::SwathMap > loadMzML	(	const std::string &	file,
		const std::string &	tmp,
		std::shared_ptr< ExperimentalSettings > &	exp_meta,
		const std::string &	readoptions = `"normal"`,
		Interfaces::IMSDataConsumer *	plugin_consumer = `nullptr`
	)

Loads a Swath run from a single mzML file.

Using the plugin_consumer, you can provide a custom consumer which will be chained into the process of loading the data and making it available (depending on readoptions). This is useful if you want to modify the data a priori or extract some other information using MSDataTransformingConsumer (for example). Make sure it leaves the data intact, such that the returned SwathMaps are actually useful.

Parameters

[in]	file	Input filename
[in]	tmp	Temporary directory (for cached data)
[out]	exp_meta	Experimental metadata from mzML file
[in]	readoptions	How are spectra accessed after reading - tradeoff between memory usage and time (disk caching)
[in]	plugin_consumer	An intermediate custom consumer

Returns: Swath maps for MS2 and MS1 (unless readoptions == split, which returns no data)

◆ loadMzXML()

std::vector< OpenSwath::SwathMap > loadMzXML	(	const std::string &	file,
		const std::string &	tmp,
		std::shared_ptr< ExperimentalSettings > &	exp_meta,
		const std::string &	readoptions = `"normal"`
	)

Loads a Swath run from a single mzXML file.

◆ loadSplit()

std::vector< OpenSwath::SwathMap > loadSplit	(	StringList	file_list,
		const std::string &	tmp,
		std::shared_ptr< ExperimentalSettings > &	exp_meta,
		const std::string &	readoptions = `"normal"`
	)

Loads a Swath run from a list of split mzML files.

◆ loadSqMass()

std::vector< OpenSwath::SwathMap > loadSqMass	(	const std::string &	file,
		std::shared_ptr< ExperimentalSettings > &
	)

Loads a Swath run from a single sqMass file.

◆ populateMetaData_()

std::shared_ptr< PeakMap > populateMetaData_ ( const std::string & file )

protected

Only read the meta data from a file and use it to populate exp_meta.
