Bio::DB::HTS::Query -- Object representing the query portion of a BAM/SAM alignment
Given an alignment retrieved from a Bio::DB::HTS database, my $query = $alignment->query; my $name = $query->display_name; my $start = $query->start; my $end = $query->end; my $dna = $query->dna; # dna string my $seq = $query->seq; # Bio::PrimarySeq object my @scores = $query->qscore; # quality score
This is a simple Bio::SeqFeatureI object that represents the query part of a SAM alignment. Methods $seqid = $query->seq_id The name of the read. $name = $query->name The read name (same as seq_id in this case). $name = $query->display_name The read display_name (same as seq_id in this case). $tag = $query->primary_tag The string "match". $tag = $query->source_tag The string "sam/bam". $start = $query->start The start of the match in read coordinates. $end = $query->end The end of the match in read coordinates; $len = $query->length The length of the read. $seq = $query->seq A Bio::PrimarySeq representing the read sequence in REFERENCE orientation. $scores = $query->qscore The read quality scores. In a list context, a list of integers equal in length to the read sequence length. In a scalar context, an array ref. The qscores are in REFERENCE sequence orientation. $dna = $query->dna The DNA string in reference sequence orientation. $strand = $query->strand If the query was reversed to align it, -1. Otherwise +1. $seq = $query->subseq($start,$end) Return a Bio::PrimarySeq object representing the requested subsequence on the read.
