DESCRIPTION

Bio::DB::GFF::Aggregator::clone is one of the default aggregators, and was written to be compatible with the C elegans GFF files. It aggregates raw Clone_left_end, Clone_right_end, and region:Genomic_canonical features into composite features of type clone.

    aggregate



 Title   : aggregate
 Usage   : $features = $a->aggregate($features,$factory)
 Function: aggregate a feature list into composite features
 Returns : an array reference containing modified features
 Args    : see L<Bio::DB::GFF::Aggregator>
 Status  : Public



The WormBase GFF model is unusual in that clones aren’t identified as a single feature with start and stop positions, but as two features, a left end and a right end. One or both of these features may be absent. In order to accommodate this, the aggregator will return undef for the start and/or stop if one or both of the ends are missing.

    method



 Title   : method
 Usage   : $aggregator->method
 Function: return the method for the composite object
 Returns : the string "clone"
 Args    : none
 Status  : Public



    part_names



 Title   : part_names
 Usage   : $aggregator->part_names
 Function: return the methods for the sub-parts
 Returns : the list ("Clone_left_end", "Clone_right_end", "region:Genomic_canonical")
 Args    : none
 Status  : Public



BUGS

None reported.
