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.

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!

Parameters

mz	The searched for mass-to-charge ratio searched
tolerance	The non-negative tolerance applied to both sides of mz

Binary search for the peak nearest to a specific m/z.

Parameters

mz	The searched for mass-to-charge ratio searched

Returns: Returns the index of the peak.

Note: Make sure the spectrum is sorted with respect to m/z! Otherwise the result is undefined.

Parameters

mz	The searched for mass-to-charge ratio searched
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

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.

◆ findNearest() [3/3]

Int findNearest	(	CoordinateType	mz,

tolerance_right	The non-negative tolerance applied right 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.; Search for the left border is done using a binary search followed by a linear scan

bool isSorted ( ) const

Checks if all peaks are sorted with respect to ascending m/z.

◆ isSorted() [2/2]

bool isSorted ( const Predicate & lambda ) const

Checks if container is sorted by a certain user-defined property.
