Detailed Description

@brief Isotope distribution approximated using linear interpolation.

This models a smoothed (widened) distribution, i.e. can be used to sample actual raw peaks (depending on the points you query). If you only want the distribution (no widening), use either EmpiricalFormula::getIsotopeDistribution() // for a certain sum formula or IsotopeDistribution::estimateFromPeptideWeight (double average_weight) // for averagine

Peak widening is achieved by either a Gaussian or Lorentzian shape.

Member Function Documentation

◆ getCenter()

CoordinateType getCenter ( ) const

overridevirtual

get the center of the Isotope model

This is a m/z-value not necessarily the monoisotopic mass.

Reimplemented from InterpolationModel.

◆ getCharge()

UInt getCharge ( ) const

◆ getFormula()

EmpiricalFormula getFormula ( )

return the Averagine peptide formula (mass calculated from mean mass and charge – use .setParameters() to set them)

◆ getIsotopeDistribution()

const IsotopeDistribution& getIsotopeDistribution ( ) const

the Isotope distribution (without widening) from the last setSamples() call

Useful to determine the number of isotopes that the model contains and their position

◆ getOffset()

CoordinateType getOffset ( )

◆ operator=()

virtual IsotopeModel& operator= ( const IsotopeModel & source )

virtual

assignment operator

◆ setOffset()

void setOffset ( CoordinateType offset )

overridevirtual

set the offset of the model

The whole model will be shifted to the new offset without being computing all over. This leaves a discrepancy which is minor in small shifts (i.e. shifting by one or two standard deviations) but can get significant otherwise. In that case use setParameters() which enforces a recomputation of the model.

Reimplemented from InterpolationModel.

◆ setSamples() [1/2]

virtual void setSamples

inlinevirtual

set sample/supporting points of interpolation (from base class)

Reimplemented from InterpolationModel.

◆ setSamples() [2/2]

virtual void setSamples ( const EmpiricalFormula & formula )

virtual

set sample/supporting points of interpolation

◆ updateMembers_()

void updateMembers_ ( )

overrideprotectedvirtual

This method is used to update extra member variables at the end of the setParameters() method.

Also call it at the end of the derived classes' copy constructor and assignment operator.

The default implementation is empty.

Reimplemented from InterpolationModel.
