Detailed Description

Scoring of an spectrum given library intensities of a transition group.

In DIA (data independent acquisition) / SWATH analysis, at each chromatographic point a full MS2 spectrum is recorded. This class allows to compute a number of scores based on the full MS2 spectrum available. The scores are the following:

See also class DIAScoring.

Simulate theoretical spectrum from library intensities of transition group and compute manhattan distance and dotprod score between spectrum intensities and simulated spectrum.

operator()()

void operator()	(	OpenSwath::SpectrumAccessPtr	swath_ptr,
		OpenSwath::LightTargetedExperiment &	transition_exp_used,
		OpenSwath::IDataFrameWriter *	ivw
	)

Compute manhattan and dotprod score for all spectra which can be accessed by the SpectrumAccessPtr for all transitions groups in the LightTargetedExperiment.

score()

void score	(	OpenSwath::SpectrumPtr	spec,
		const std::vector< OpenSwath::LightTransition > &	lt,
		double &	dotprod,
		double &	manhattan
	)

Score a spectrum given a transition group.

updateMembers_()

void updateMembers_ ( )

overridevirtual

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 DefaultParamHandler.
