Detailed Description

Class to represent a mass spectrum.

A mass spectrum is a collection of DataPoint instances. Moreover, it has internal data that represent the context of the acquisition of the data: retention time and drift time (if the experiment was an ion mobility mass spectrometry experiment).

A MassSpectrum cannot perform combinations. For combination of mass spectra, the class to use is MassSpectrumCombinator.

◆ equals()

bool pappso::MassSpectrum::equals ( const MassSpectrum other,

Tells if this MassSpectrum is equal to massSpectrum.

To compare this to massSpectrum, a tolerance is applied to both the x and y values, that is defined using precision.

Parameters
massSpectrumMass spectrum to compare to this.
precisionPrecision to be used to perform the comparison of the x and y values of the data points in this and \massSpectrum mass spectra.
