◆ PredictorMfe()

IntaRNA::PredictorMfe::PredictorMfe	(	const InteractionEnergy &	energy,
		OutputHandler &	output,
		PredictionTracker *	predTracker
	)

Construction call the super constructor

Parameters

energy	the interaction energy handler
output	the output handler to report optimal interactions to
predTracker	the prediction tracker to be used or NULL if no tracking is to be done; if non-NULL, the tracker gets deleted on this->destruction.

Member Function Documentation

◆ getNextBest()

virtual void IntaRNA::PredictorMfe::getNextBest ( Interaction & curBest )

protectedvirtual

Identifies the next best interaction with an energy equal to or higher than the given interaction. The new interaction will not overlap any index range stored in reportedInteractions.

Parameters

curBest IN/OUT the current best interaction to be replaced with one of equal or higher energy not overlapping with any reported interaction so far; an interaction with energy E_INF is set, if there is no better interaction left

Reimplemented in IntaRNA::PredictorMfe2dHelixBlockHeuristic, IntaRNA::PredictorMfe2dHelixBlockHeuristicSeed, IntaRNA::PredictorMfe2dHeuristic, IntaRNA::PredictorMfe2dHeuristicSeed, and IntaRNA::PredictorSeedExtensionKinetic.

◆ initOptima()

virtual void IntaRNA::PredictorMfe::initOptima ( )

protectedvirtual

Initializes the global energy minimum storage

Implements IntaRNA::Predictor.

◆ isValidOutputSite()

bool IntaRNA::PredictorMfe::isValidOutputSite	(	const size_t	i1,
		const size_t	j1,
		const size_t	i2,
		const size_t	j2
	)		const

protected

Checks terminal GU and accessibility constraints for a complete site. Recursion cells may be useful extensions without being valid output sites.

Parameters

i1	inclusive start in sequence 1, relative to the energy offset
j1	inclusive end in sequence 1, relative to the energy offset
i2	inclusive start in reversed sequence 2, relative to its offset
j2	inclusive end in reversed sequence 2, relative to its offset

Returns: whether both terminal pairs and ED penalties satisfy output limits

◆ reportOptima()

virtual void IntaRNA::PredictorMfe::reportOptima ( )

protectedvirtual

Calls for the stored mfe and suboptimal solutions traceBack(i) and pushes the according interactions to the output handler. For non-overlapping interaction enumeration, getNextBest() is called iteratively.

Implements IntaRNA::Predictor.

Reimplemented in IntaRNA::PredictorMfeEns.

◆ traceBack()

virtual void IntaRNA::PredictorMfe::traceBack ( Interaction & interaction )

protectedpure virtual

Fills a given interaction (boundaries given) with the according hybridizing base pairs. Note, the

Parameters

interaction IN/OUT the interaction to fill

j1	interaction end in seq1
i2	interaction start in seq2
i2	interaction end in seq2
curInteraction	the interaction information to be used for update

updates the global optimum to be the mfe interaction if needed

Parameters

i1	the index of the first sequence interacting with i2
j1	the index of the first sequence interacting with j2
i2	the index of the second sequence interacting with i1
j2	the index of the second sequence interacting with j1
energy	the energy of the interaction
isHybridE	whether or not the given energy is only the hybridization energy (init+loops) or the total interaction energy
