Member Function Documentation

DNA & DNA::operator=

(

const DNA &

s

)

References bioseq::operator=().

DNA & DNA::operator=

(

const string &

str

)

replace the underlying sequece with str

Reimplemented from bioseq.

References bioseq::operator=().

Protein DNA::translate

(

)

const

this is one essential operationn with cDNA CDS features of genomic DNA also use this feature.

References codontable, and bioseq::seq.

Referenced by longestORFForward(), main(), GenModel::makeProtein(), and GenModel::valid().

Protein DNA::translate	(	int	begin,
		int	end = -1
	)			const

use 1-based index This operation limits the operation to a subrange of the DNA sequence. This class use only one codon table that is static.

References codontable, and bioseq::seq.

DNA DNA::subseq	(	int	b,
		int	e
	)			const [inline]

performance is very bad if sequence is long. 1-based index, inclusive [b, e]

Reimplemented from bioseq.

References bioseq::subseq().

Referenced by bufferGenomic(), buildGeneInfo(), dumpFromModel(), dumpIntronExon(), and main().

const int * DNA::getcodeNuc

(

)

const

not implemented yet, could convert bases into integers like A=>0, C=>1, ... This method is different, use a different hashing method

References bioseq::code, hashbase(), bioseq::length(), and bioseq::seq.

sequenceType DNA::getSequenceType

(

)

const [inline, virtual]

Reimplemented from bioseq.

References DNASEQ.

double DNA::GCContent

(

)

const

return the fraction of GC/Length of sequence

References at, and bioseq::seq.

Referenced by dumpFromModel(), and dumpIntronExon().

void DNA::revcomp

(

)

[inline]

use the inplace global function more efficient

References reverseComplementInPlace(), and bioseq::seq.

Referenced by ESTModel::ESTModel(), longestORFReverse(), and mRNAModel::mRNAModel().

Protein DNA::longestORFForward	(	int &	b,
		int &	e
	)			const

return the longest peptide sequence in the + strand. set b,e to the range on DNA that give rise to this translation. b,e are C style index. [b,e)

References bioseq::length(), longestORFIndex(), bioseq::subsequence(), and translate().

Referenced by ESTModel::ESTModel(), longestORF(), longestORFReverse(), mRNAModel::mRNAModel(), and testTranslate().

void DNA::longestORFForward	(	Protein &	p,
		int &	b,
		int &	e
	)			const

more efficient version, avoiding returning a long string.

References bioseq::length(), longestORFIndex(), bioseq::subsequence(), and translate().

Protein DNA::longestORFReverse	(	int &	b,
		int &	e
	)			const

[b,e) b>e from the lower strand (-)

[inline, static]

References codontable.

Member Data Documentation

codon DNA::codontable = codon() [static, protected]

all the DNA class use one codon table This is mostly for efficiency purposes. May have to add some other function to deal with particular codon tables.

Referenced by getCodonTable(), and translate().
