NAME

Bio::SeqFeature::SimilarityPair - Sequence feature based on the similarity of two sequences.

SYNOPSIS

$sim_pair = Bio::SeqFeature::SimilarityPair->from_searchResult($blastHit);

$sim = $sim_pair->query(); # a Bio::SeqFeature::Similarity object - the query
$sim = $sim_pair->hit();   # dto - the hit.

# some properties for the similarity pair
$expect = $sim_pair->significance();
$score = $sim_pair->score();
$bitscore = $sim_pair->bits();

# this will not write the description for the sequence (only its name)
print $sim_pair->query()->gff_string(), "\n";

DESCRIPTION

Lightweight similarity search result as a pair of Similarity features. This class inherits off Bio::SeqFeature::FeaturePair and therefore implements Bio::SeqFeatureI, whereas the two features of the pair are descendants of Bio::SeqFeature::Generic, with better support for representing similarity search results in a cleaner way.
