Ace::Sequence::Transcript - Simple "Gene" Object
Contents
Description
Ace::Sequence::Gene is a subclass of Ace::Sequence::Feature. It inherits all the methods of
Ace::Sequence::Feature, but adds the ability to retrieve the annotated introns and exons of the gene.
Name
Ace::Sequence::Transcript - Simple "Gene" Object
Object Creation
You will not ordinarily create an Ace::Sequence::Gene object directly. Instead, objects will be created
in response to a transcripts() call to an Ace::Sequence object.
Object Methods
Most methods are inherited from Ace::Sequence::Feature. The following methods are also supported:
exons()
@exons = $gene->exons;
Return a list of Ace::Sequence::Feature objects corresponding to annotated exons.
introns()
@introns = $gene->introns;
Return a list of Ace::Sequence::Feature objects corresponding to annotated introns.
cds()
@cds = $gene->cds;
Return a list of Ace::Sequence::Feature objects corresponding to coding sequence. THIS IS NOT YET
IMPLEMENTED.
relative()
$relative = $gene->relative;
$gene->relative(1);
This turns on and off relative coordinates. By default, the exons and intron features will be
returned in the coordinate system used by the gene. If relative() is set to a true value, then
coordinates will be expressed as relative to the start of the gene. The first exon will (usually) be
1.

Synopsis
# open database connection and get an Ace::Object sequence
use Ace::Sequence;
# get a megabase from the middle of chromosome I
$seq = Ace::Sequence->new(-name => 'CHROMOSOME_I,
-db => $db,
-offset => 3_000_000,
-length => 1_000_000);
# get all the transcripts
@genes = $seq->transcripts;
# get the exons from the first one
@exons = $genes[0]->exons;
# get the introns
@introns = $genes[0]->introns
# get the CDSs (NOT IMPLEMENTED YET!)
@cds = $genes[0]->cds;
