Detailed Description

In-Memory representation of a mass spectrometry experiment.

Contains the data and metadata of an experiment performed with an MS (or HPLC and MS). This representation of an MS experiment is organized as list of spectra and chromatograms and provides an in-memory representation of popular mass-spectrometric file formats such as mzXML or mzML. The meta-data associated with an experiment is contained in ExperimentalSettings (by inheritance) while the raw data (as well as spectra and chromatogram level meta data) is stored in objects of type MSSpectrum and MSChromatogram, which are accessible through the getSpectrum and getChromatogram functions.

Be careful when changing the order of contained MSSpectrum instances, if tandem-MS data is stored in this class. The only way to find a precursor spectrum of MSSpectrum x is to search for the first spectrum before x that has a lower MS-level!

Note: For range operations, see RangeUtils module!; Some of the meta data is associated with the spectra directly (e.g. DataProcessing) and therefore the spectra need to be present to retain this information.; For an on-disc representation of an MS experiment, see OnDiskExperiment.

◆ RTBegin() [1/2]

Iterator RTBegin ( CoordinateType rt )

Fast search for spectrum range begin.

Note: Make sure the spectra are sorted with respect to retention time! Otherwise the result is undefined.

◆ RTBegin() [2/2]

ConstIterator RTBegin ( CoordinateType rt ) const

Fast search for spectrum range begin.

Returns the first scan which has equal or higher (>=) RT than rt.

Note: Make sure the spectra are sorted with respect to retention time! Otherwise the result is undefined.

◆ RTEnd() [1/2]

Iterator RTEnd ( CoordinateType rt )

Fast search for spectrum range end (returns the past-the-end iterator)

Note: Make sure the spectra are sorted with respect to retention time! Otherwise the result is undefined.

◆ RTEnd() [2/2]

ConstIterator RTEnd ( CoordinateType rt ) const

Fast search for spectrum range end (returns the past-the-end iterator)

Returns the first scan which has higher (>) RT than rt.

Note: Make sure the spectra are sorted with respect to retention time! Otherwise the result is undefined.

◆ set2DData() [1/3]

void set2DData ( const Container & container )

inline

Assignment of a data container with RT and MZ to an MSExperiment.

Fill MSExperiment with data. Note that all data present (including meta-data) will be deleted prior to adding new data!

Parameters

container An iterable type whose elements support getRT(), getMZ() and getIntensity()

Exceptions

Exception::Precondition is thrown if the container is not sorted according to retention time (in debug AND release mode)

◆ set2DData() [2/3]

void set2DData ( const Container & container )

inline

Assignment of a data container with RT and MZ to an MSExperiment.

Fill MSExperiment with data. Note that all data present (including meta-data) will be deleted prior to adding new data!

Parameters

container	An iterable type whose elements support getRT(), getMZ() and getIntensity()
add_mass_traces	If true, each container element is searched for the metavalue "num_of_masstraces". If found, "masstrace_intensity" (X>=0) meta values are added as data points (with 13C spacing). This is useful for, e.g., FF-Metabo output. Note that the actual feature will NOT be added if mass traces are found (since MT0 is usually identical)

Exceptions

Exception::Precondition is thrown if the container is not sorted according to retention time (in debug AND release mode) OR a "masstrace_intensity" value is expected but not found

◆ set2DData() [3/3]

void set2DData	(	const Container &	container,
		const StringList &	store_metadata_names
	)

inline

Assignment of a data container with RT and MZ to an MSExperiment.

Fill MSExperiment with data. Note that all data present (including meta-data) will be deleted prior to adding new data!

Parameters

container	An iterable type whose elements support getRT(), getMZ() and getIntensity()
store_metadata_names	[MetaInfoInterface input only] Names of metadata arrays which should be created; data is filled from the metainfointerface of each element of the input container. Currently, only float data is supported!

Exceptions

Exception::Precondition is thrown if the container is not sorted according to retention time (in debug AND release mode)

◆ setChromatograms()

void setChromatograms ( const std::vector< MSChromatogram > & chromatograms )

◆ setSpectra()

void setSpectra ( const std::vector< MSSpectrum > & spectra )

◆ sortChromatograms()

void sortChromatograms ( bool sort_rt = true )

Sorts the data points of the chromatograms by m/z.

Parameters

sort_rt if true, chromatograms are sorted by rt position as well

◆ sortSpectra()

void sortSpectra ( bool sort_mz = true )

Sorts the data points by retention time.

Parameters

sort_mz if true, spectra are sorted by m/z position as well

◆ swap()

void swap ( MSExperiment & from )

Swaps the content of this map with the content of from.

◆ updateRanges() [1/2]

void updateRanges ( )

overridevirtual

Updates minimum and maximum position/intensity.

This method is usually implemented by calling clearRanges() and updateRanges_().

Implements RangeManager< 2 >.

◆ updateRanges() [2/2]

void updateRanges ( Int ms_level )

Updates the m/z, intensity, retention time and MS level ranges of all spectra with a certain ms level.

Parameters

ms_level MS level to consider for m/z range , RT range and intensity range (All MS levels if negative)
