Detailed Description

The SequenceRev class implements the Sequence abstract class for accessing the reverse sequence.

Documentation is only provided for methods not documented in the abstract Sequence class and SequenceFwd class. This class acts by storing a pointer to a SequenceFwd object and reverse complementing

the input and output appropriately.

void SequenceRev::calc_p_vals ( std::vector< double > & p_vals ) const [virtual]

A member function that calculates p-values based on the observed and expected nucleotide frequences for the sequence.

Experimental.

Parameters:

p_vals a reference to an empty vector of doubles to fill with p-values at each position.

Implements Sequence.

Definition at line 119 of file sequence.cpp.

bool SequenceRev::empty ( ) const [inline, virtual]

Accessor to determine if the sequence has 0 length.

Returns:: True iff the sequence has 0 length.

Implements Sequence.

Definition at line 274 of file sequence.h.

float SequenceRev::get_exp	(	const size_t	index,
		const size_t	nuc
	)		const `[inline, virtual]`

An accessor for the expected nucleotide frequency (logged).

Parameters:

index	the index of the position to access.
nuc	the nucleotide to return the frequency of.

Returns:: The logged expected frequency of the given nucleotide a the given position.

Implements Sequence.

Definition at line 288 of file sequence.h.

float SequenceRev::get_obs	(	const size_t	index,
		const size_t	nuc
	)		const `[inline, virtual]`

An accessor for the observed nucleotide frequency (logged).

Parameters:

index	the index of the position to access.
nuc	the nucleotide to return the frequency of.

Returns:: The logged observed frequency of the given nucleotide a the given position.

Implements Sequence.

Definition at line 286 of file sequence.h.

float SequenceRev::get_prob	(	const size_t	index,
		const size_t	nuc
	)		const `[inline, virtual]`

An accessor for the posterior nucleotide distribution (logged).

Parameters:

index	the index of the position to access.
nuc	the nucleotide to return the probability of.

Returns:: The logged posterior probability of the given nucleotide at the given position.

Implements Sequence.

Definition at line 296 of file sequence.h.

size_t SequenceRev::get_ref ( const size_t index ) const [inline, virtual]

An accessor for the encoded reference character at the given index.

May differ from the operator[] if the sequence is probabilistic.

Parameters:

index the index of the encoded reference character to return (assumed to be < _len)

Returns:: The encoded reference character at the given index.

Implements Sequence.

Definition at line 284 of file sequence.h.
