Member Function Documentation

void LocARNA::ExtRnaDataImpl::drop_worst_bpil

(

size_t

keep

)

Drop base pairs in loops with lowest probability.

Parameters:

keep	the maximum total number of base pairs in loops to keep

void LocARNA::ExtRnaDataImpl::drop_worst_bpil_precise

(

double

ratio

)

Drop base pairs in loops with lowest probability based on loop length.

Parameters:

ratio

limit on number of base pairs closed by a loop divided by loop length

void LocARNA::ExtRnaDataImpl::drop_worst_bps

(

size_t

keep

)

Drop in loop bases and base pairs without base pairs.

Parameters:

keep	the maximum number of base pairs to keep

void LocARNA::ExtRnaDataImpl::drop_worst_uil

(

size_t

keep

)

Drop unpaired bases in loops with lowest probability.

Parameters:

keep	the maximum total number of unpaired bases in loops to keep

void LocARNA::ExtRnaDataImpl::init_from_ext_rna_ensemble

(

const RnaEnsemble &

rna_ensemble

)

initialize from rna ensemble

Parameters:

rna_ensemble

rna ensemble

Note:

overloaded to initialize with additional information (in loop probabilities)

rna_ensemble must have in loop probabilities

void LocARNA::ExtRnaDataImpl::init_from_fixed_structure

(

const RnaStructure &

)

initialize in loop probabilities from fixed structure

Parameters:

structure

fixed structure

Note:

this initializes only the inloop probabilities; itdoes not initialize base pair probabilities, which is done by the corresponding method of RnaDataImpl.

stream

Reads only base pairs with probabilities greater than p_bpcut_; base pairs in loops, p_bpilcut_; unpaired bases in loops, p_uilcut_
