6 Ace::Sequence::Homol - Temporary Sequence Homology Class
7
9 # Get all similarity features from an Ace::Sequence
10 @homol = $seq->features('Similarity');
11
12 # sort by score
13 @sorted = sort { $a->score <=> $b->score } @homol;
14
15 # the last one has the highest score
16 $best = $sorted[$#sorted];
17
18 # fetch its associated Ace::Sequence::Homol
19 $homol = $best->target;
20
21 # print out the sequence name, DNA, start and end
22 print $homol->name,' ',$homol->start,'-',$homol->end,"\n";
23 print $homol->asDNA;
24
26 Ace::Sequence::Homol is a subclass of Ace::Object (not Ace::Sequence)
27 which is specialized for returning information about a DNA or protein
28 homology. This is a temporary placeholder for a more sophisticated
29 homology class which will include support for alignments.
30
32 You will not ordinarily create an Ace::Sequence::Homol object directly.
33 Instead, objects will be created in response to an info() or group()
34 method call on a similarity feature in an Ace::Sequence::Feature
35 object. If you wish to create an Ace::Sequence::Homol object directly,
36 please consult the source code for the new() method.
37
39 Most methods are inherited from Ace::Object. The following methods are
40 also supported:
41
42 start()
43 $start = $homol->start;
44
45 Returns the start of the area that is similar to the
46 Ace::Sequence::Feature from which his homology was derived.
47 Coordinates are relative to the target homology.
48
49 end()
50 $end = $homol->end;
51
52 Returns the end of the area that is similar to the
53 Ace::Sequence::Feature from which his homology was derived.
54 Coordinates are relative to the target homology.
55
56 asString()
57 $label = $homol->asString;
58
59 Returns a human-readable identifier describing the nature of the
60 feature. The format is:
61
62 $name/$start-$end
63
64 for example:
65
66 HUMGEN13/1-67
67
68 This method is also called automatically when the object is treated
69 in a string context.
