Bio::DB::GFF::Aggregator::match_gap(3) GFF3 match aggregator


Aggregator method: match_gap
Main method: match
Sub methods: match


This aggregator is used for GFF3 style gapped alignments, in which there is a single feature of method 'match' with a 'Gap' attribute.

The 'Gap' attribute's format consists of a series of (operartion,length) pairs separated by space characters, for example: 'M8 D3 M6'. (see GFF reference for complete explanation)

This module only recognizes the M and D operators, which should be sufficient for simple nucleotide to nucleotide alignments.


None reported.
