# Bio::DB::GFF::Aggregator::waba\_alignment(3pm)

## NAME

Bio::DB::GFF::Aggregator::waba\_alignment -- A WABA alignment

## SYNOPSIS

```
  use Bio::DB::GFF;
  # Open the sequence database
  my $db      = Bio::DB::GFF->new( -adaptor => 'dbi:mysql',
                                   -dsn     => 'dbi:mysql:elegans42',
                                   -aggregator => ['waba_alignment'],
                                 );
  # fetch the synthetic feature type "waba_alignment"
  my @waba    = $db->features('waba_alignment');
 -------------------------------------------------------------------------------------
 Aggregator method: waba_alignment
 Main method:       -none
 Sub methods:       nucleotide_match:waba_weak nucleotide_match:waba_strong
                    nucleotide_match::waba_coding
 -------------------------------------------------------------------------------------
```

## DESCRIPTION

Bio::DB::GFF::Aggregator::waba\_alignment handles the type of alignments produced by Jim Kent's WABA program, and was written to be compatible with the C elegans GFF files.  It aggregates the following feature types into an aggregate type of "waba\_alignment":

```
   nucleotide_match:waba_weak
   nucleotide_match:waba_strong
   nucleotide_match:waba_coding
```

### method

```

### part\_names

```
 Title   : part_names
