Function Documentation

Codon seq_codonVal

(

DNA *

start

)

Return value from 0-63 of codon starting at start.

Returns -1 if not a codon.

Definition at line 264 of file seq.c.

int seq_intronOrientation	(	DNA *	iStart,
		DNA *	iEnd
	)

Given a gap in genome from iStart to iEnd, return 1 for GT/AG intron between left and right, -1 for CT/AC, 0 for no intron.

Assumes DNA is lower cased.

Definition at line 615 of file seq.c.

aaSeq* seq_translateSeq	(	dnaSeq *	inSeq,
		unsigned	offset,
		int	stop
	)

Return a translated sequence.

Offset is position of first base to translate. If stop is 1 then stop at first stop codon. (Otherwise represent stop codons as 'Z').

Definition at line 505 of file seq.c.

aaSeq* seq_translateSeqN	(	dnaSeq *	inSeq,
		unsigned	offset,
		unsigned	inSize,
		int	stop
	)

Return a translated sequence.

Offset is position of first base to translate. If size is 0 then use length of inSeq.
