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.

FEEDBACK ^

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Support

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

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
