NAME
Bio::Tools::Spidey::Exon - A single exon determined by an alignment SYNOPSIS
# See Bio::Tools::Spidey::Results for a description of the context. # an instance of this class is-a Bio::SeqFeature::SimilarityPair # coordinates of the exon (recommended way): print "exon from ", $exon->start(), " to ", $exon->end(), " "; # the same (feature1() inherited from Bio::SeqFeature::FeaturePair) print "exon from ", $exon->feature1()->start(), " to ", $exon->feature1()->end(), " "; # also the same (query() inherited from Bio::SeqFeature::SimilarityPair): print "exon from ", $exon->query()->start(), " to ", $exon->query()->end(), " "; # coordinates on the matching EST (recommended way): print "matches on EST from ", $exon->est_hit()->start(), " to ", $exon->est_hit()->end(), " "; # the same (feature2() inherited from Bio::SeqFeature::FeaturePair) print "matches on EST from ", $exon->feature2()->start(), " to ", $exon->feature2()->end(), " "; # also the same (subject() inherited from Bio::SeqFeature::SimilarityPair): print "exon from ", $exon->subject()->start(), " to ", $exon->subject()->end(), " "; DESCRIPTION
This class inherits from Bio::SeqFeature::SimilarityPair and represents an exon on a genomic sequence determined by similarity, that is, by aligning an EST sequence (using Spidey in this case). Consequently, the notion of query and subject is always from the perspective of the genomic sequence: query refers to the genomic seq, subject to the aligned EST hit. Because of this, $exon->start(), $exon->end() etc will always return what you expect. To get the coordinates on the matching EST, refer to the properties of the feature returned by est_hit(). 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. bioperl-l@bioperl.org - General discussion http://bioperl.org/wiki/Mailing_lists - About the mailing lists 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. Reporting Bugs Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web: https://redmine.open-bio.org/projects/bioperl/ AUTHOR - Ryan Golhar Email golharam@umdnj.edu APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _ percentage_id Title : percentage_id Usage : $obj->percentage_id Function: This is the percent id as reported by Spidey Returns : value of percentage_id Args : est_hit Title : est_hit Usage : $est_feature = $obj->est_hit(); Function: Returns the EST hit pointing to (i.e., aligned to by Spidey) this exon (i.e., genomic region). At present, merely a synonym for $obj->feature2(). Returns : An Bio::SeqFeatureI implementing object. Args : mismatches Title : mismatches Usage : $obj->mismatches; Function: Returns the mismatches of the cDNA to (i.e., aligned to by Spidey) this exon (i.e., genomic region). Returns : value of mismatches. Args : gaps Title : gaps Usage : $obj->gaps; Function: Returns the gaps of the cDNA to (i.e., aligned to by Spidey) this exon (i.e., genomic region). Returns : value of gaps. Args : donor Title : donor Usage : $obj->donor; Function: Returns 0 if a splice donor site does not exist, or 1 if a splice donor site exists Returns : value of existence of donor splice site (0 or 1) Args : acceptor Title : acceptor Usage : $obj->acceptor; Function: Returns 0 if a splice acceptor site does not exist, or 1 if a splice acceptor site exists Returns : value of existence of acceptor splice site (0 or 1) Args : perl v5.14.2 2012-03-02 Bio::Tools::Spidey::Exon(3pm)
