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!

tolerance	The 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

Returns: Returns the index of the peak or -1 if no peak present in tolerance window or if spectrum is empty

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()

Lexicographically sorts the peaks by their intensity.

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

◆ sortByPosition()

void sortByPosition ( )

Lexicographically sorts the peaks by their position.

The spectrum is sorted with respect to position. Meta data arrays will be sorted accordingly.

◆ sortByPositionPresorted()

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

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

Parameters

chunks a 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

implement this function to reflect the underlying data of the derived class (e.g. an MSSpectrum) Usually, call clearRanges() internally and then populate the dimensions.

Implements RangeManagerContainer< RangeMZ, RangeIntensity >.
