◆ EdMatrix

typedef UpperBandedMatrix<E_type> IntaRNA::AccessibilityVrna::EdMatrix

protected

type for the ED value matrix (upper triangular matrix banded by maxLength)

Constructor & Destructor Documentation

◆ AccessibilityVrna()

IntaRNA::AccessibilityVrna::AccessibilityVrna	(	const RnaSequence &	sequence,
		const size_t	maxLength,
		const AccessibilityConstraint *const	accConstraint,
		const VrnaHandler &	vrnaHandler,
		const size_t	plFoldW = `0`,
		const double	pfScale = `VrnaHandler::getPfScaleDefault()`
	)

Construction

Parameters

sequence	the sequence the accessibility data belongs to
maxLength	the maximal window size of accessible regions to be considered. 0 defaults to the sequence's length.
accConstraint	if not NULL, accessibility constraint that enforces some regions to be unstructured both in sequence and interaction
vrnaHandler	the VRNA parameter handler to be used
plFoldW	the sliding window size to be used for plFold computations @oaram pfScale can be used to explicitly set pf_scale of VRNA partition function computation. Note: only used for values >= 1.0, all other values are ignored.

◆ addConstraints()

static void IntaRNA::AccessibilityVrna::addConstraints	(	vrna_fold_compound_t &	fold_compound,
		const Accessibility &	acc
	)

static

Adds constraints to the VRNA fold compound that correspond to the present AccessibilityConstraints

Parameters

fold_compound	INOUT the object to extend
acc	the accessibility handler to get constraint information from

◆ callbackForStorage()

callback function used when calling vrna_probs_window()

This function will be called for each probability data set in the sliding window probability computation implementation of vrna_probs_window(). The argument type specifies the type of probability that is passed to this function.

See also: vrna_probs_window()

Parameters

pr	An array of probabilities
pr_size	The length of the probability array
j	The j-position (3'-end) of the probability intervals (indexing starting with 1)
max	The (theoretical) maximum length of the probability array
type	The type of probability that is passed to this function
storageRT	Auxiliary data: should hold a pair(AccessibilityVrna*,double RT)

◆ fillByRNAplfold()

void IntaRNA::AccessibilityVrna::fillByRNAplfold	(	const VrnaHandler &	vrnaHandler,
		const size_t	plFoldW,
		const size_t	plFoldL,
		const double	pfScale
	)

protected

Use RNAplfold-like style to fill ED-values

Parameters

vrnaHandler	the VRNA handler to be used
plFoldW	the sliding window size to be used or 0 for full length
plFoldL	the maximal base pair span to be used or 0 for plFoldW @oaram pfScale can be used to explicitly set pf_scale of VRNA partition function computation. Note: only used for values >= 1.0, all other values are ignored.

◆ getED()

E_type IntaRNA::AccessibilityVrna::getED	(	const size_t	from,
		const size_t	to
	)		const

inlinevirtual

Returns the accessibility energy value for the given range in the sequence, i.e. the energy difference (ED) to make the region accessible.

Parameters

from	the start index of the regions (from <= to)
to	the end index of the regions (to < seq.length)

Returns: the ED value if (j-1+1) <= maxLength or ED_UPPER_BOUND otherwise

Exceptions

std::runtime_error in case it does not hold 0 <= from <= to < seq.length

Implements IntaRNA::Accessibility.

◆ writeBinary()

void IntaRNA::AccessibilityVrna::writeBinary ( std::ostream & out ) const

inlineoverridevirtual

Write the stored ED matrix directly, without copying rows or calling getED() for unconstrained data. Constraints retain the generic getED() path. Subclasses changing getED() semantics must also override this method.

Parameters

out	binary output stream; compression is supplied by the stream

Reimplemented from IntaRNA::Accessibility.
