Bio::SeqFeature::SimilarityPair(3)

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.

  Support
Please direct usage questions or support issues to the mailing list:
