NAME

6       Ace::Sequence::Gene - Simple "Gene" Object
7

SYNOPSIS

9           # open database connection and get an Ace::Object sequence
10           use Ace::Sequence;
11
12           # get a megabase from the middle of chromosome I
13           $seq = Ace::Sequence->new(-name   => 'CHROMOSOME_I,
14                                     -db     => $db,
15                                     -offset => 3_000_000,
16                                     -length => 1_000_000);
17
18           # get all the genes
19           @genes = $seq->genes;
20
21           # get the exons from the first one
22           @exons = $genes[0]->exons;
23
24           # get the introns
25           @introns = $genes[0]->introns
26
27           # get the CDSs (NOT IMPLEMENTED YET!)
28           @cds = $genes[0]->cds;

DESCRIPTION

31       Ace::Sequence::Gene is a subclass of Ace::Sequence::Feature.  It
32       inherits all the methods of Ace::Sequence::Feature, but adds the
33       ability to retrieve the annotated introns and exons of the gene.
34

OBJECT CREATION

36       You will not ordinarily create an Ace::Sequence::Gene object directly.
37       Instead, objects will be created in response to a genes() call to an
38       Ace::Sequence object.
39

OBJECT METHODS

41       Most methods are inherited from Ace::Sequence::Feature.  The following
42       methods are also supported:
43
44       exons()
45             @exons = $gene->exons;
46
47           Return a list of Ace::Sequence::Feature objects corresponding to
48           annotated exons.
49
50       introns()
51             @introns = $gene->introns;
52
53           Return a list of Ace::Sequence::Feature objects corresponding to
54           annotated introns.
55
56       cds()
57             @cds = $gene->cds;
58
59           Return a list of Ace::Sequence::Feature objects corresponding to
60           coding sequence.  THIS IS NOT YET IMPLEMENTED.
61
62       relative()
63             $relative = $gene->relative;
64             $gene->relative(1);
65
66           This turns on and off relative coordinates.  By default, the exons
67           and intron features will be returned in the coordinate system used
68           by the gene.  If relative() is set to a true value, then
69           coordinates will be expressed as relative to the start of the gene.
70           The first exon will (usually) be 1.
