NAME

       Bio::DB::GFF::Util::Binning - binning utility for Bio::DB::GFF index

SYNOPSIS

        use Bio::DB::GFF::Util::Binning qw(bin bin_bot bin_top);
        my $tier = bin($start,$stop,$min);

DESCRIPTION

       This is a utility module that exports the functions bin(), bin_bot() and bin_top().  These
       functions translate a range on the genome into a named bin that is used as an index in the
       Bio::DB::GFF schema.  The index makes certain range retrieval queries much faster.

API

       The remainder of the document describes the function calls.  No calls are exported by
       default, but must be imported explicitly.

       $bin_name = bin($start,$stop,$bin_size)
           Given a start, stop and bin size on the genome, translate this location into a bin
           name.  In a list context, returns the bin tier name and the position that the bin
           begins.

       $bottom = bin_bot($tier,$start)
           Given a tier name and a range start position, returns the lower end of the bin range.

       $top = bin_top($tier,$end)
           Given a tier name and the end of a range, returns the upper end of the bin range.

BUGS

       None known yet.
