Peak data array methods

These methods are used to annotate each peak in a spectrum with meta information. It is an intermediate way between storing the information in the peak's MetaInfoInterface and deriving a new peak type with members for this information.

These statements should help you chose which approach to use

  • Access to meta info arrays is slower than to a member variable
  • Access to meta info arrays is faster than to a MetaInfoInterface
  • Meta info arrays are stored when using mzML format for storing

Detailed Description

The representation of a 1D spectrum.

It contains peak data and metadata about specific instrument settings, acquisition settings, description of the meta values used in the peaks and precursor info (SpectrumSettings).

Several MSSpectrum instances are contained in a peak map (MSExperiment), which is essentially a vector of spectra with additional information about the experiment.

Precursor info from SpectrumSettings should only be used if this spectrum is a tandem-MS spectrum. The precursor spectrum is the first spectrum in MSExperiment, that has a lower MS-level than the current spectrum.

Note
For range operations, see RangeUtils module!

toleranceThe non-negative tolerance applied to both sides of mz
Returns
Returns the index of the peak or -1 if no peak present in tolerance window or if spectrum is empty
Note
Make sure the spectrum is sorted with respect to m/z! Otherwise the result is undefined.
Peaks exactly on borders are considered in tolerance window.

Parameters
mzThe searched for mass-to-charge ratio searched

Returns the ion mobility drift time (MSSpectrum::DRIFTTIME_NOT_SET means it is not set)

Note
Drift times may be stored directly as an attribute of the spectrum (if they relate to the spectrum as a whole). In case of ion mobility spectra, the drift time of the spectrum will always be set here while the drift times attribute in the Precursor class may often be unpopulated.

◆ select()

MSSpectrum& select ( const std::vector< Size > &  indices)

◆ setDriftTime()

void setDriftTime ( double  dt)

Sets the ion mobility drift time.

◆ setDriftTimeUnit()

void setDriftTimeUnit ( DriftTimeUnit  dt)

Sets the ion mobility drift time unit.

◆ setFloatDataArrays()

void setFloatDataArrays ( const FloatDataArrays fda)

Sets the float meta data arrays.

◆ setIntegerDataArrays()

void setIntegerDataArrays ( const IntegerDataArrays ida)

Sets the integer meta data arrays.

◆ setMSLevel()

void setMSLevel ( UInt  ms_level)

◆ setName()

void setName ( const String name)

◆ setRT()

void setRT ( double  rt)

◆ setStringDataArrays()

void setStringDataArrays ( const StringDataArrays sda)

Sets the string meta data arrays.

◆ sort()

void sort ( const Predicate &  lambda)
inline

Sort by a user-defined property You can pass any lambda function with [](Size index_1, Size index_2) –> bool which given two indices into MSSpectrum (either for peaks or data arrays) returns a weak-ordering. (you need to capture the MSSpectrum in the lambda and operate on it, based on the indices)

◆ sortByIntensity()

void sortByIntensity ( bool  reverse = false)

Lexicographically sorts the peaks by their intensity.

Sorts the peaks according to ascending intensity. Meta data arrays will be sorted accordingly.

Referenced by WindowMower::filterPeakSpectrumForTopNInSlidingWindow(), NLargest::filterSpectrum(), and Scaler::filterSpectrum().

◆ sortByPosition()

void sortByPosition ( )

◆ sortByPositionPresorted()

void sortByPositionPresorted ( const std::vector< Chunk > &  chunks)

Sort the spectrum, but uses the fact, that certain chunks are presorted.

Parameters
chunksa Chunk is an object that contains the start and end of a sublist of peaks in the spectrum, that is or isn't sorted yet (is_sorted member)

◆ updateRanges()

void updateRanges ( )
overridevirtual

Updates minimum and maximum position/intensity.

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

Implements RangeManager< 1 >.
