Bio::Variation::Allele(3) User Contributed Perl Documentation Bio::Variation::Allele(3)

Bio::Variation::Allele - Sequence object with allele-specific attributes

  $allele1 = Bio::Variation::Allele->new ( -seq => 'A',
                                           -id  => 'AC00001.1',
                                           -alphabet => 'dna',
                                           -is_reference => 1

List of alleles describe known sequence alternatives in a variable region. Alleles are contained in Bio::Variation::VariantI complying objects. See Bio::Variation::VariantI for details.
Bio::Varation::Alleles are PrimarySeqI complying objects which can contain database cross references as specified in Bio::DBLinkContainerI interface, too.
A lot of the complexity with dealing with Allele objects are caused by null alleles; Allele objects that have zero length sequence string.
In addition describing the allele by its sequence , it possible to give describe repeat structure within the sequence. This done using methods repeat_unit (e.g. 'ca') and repeat_count (e.g. 7).

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing lists Your participation is much appreciated.                  - General discussion  - About the mailing lists

Please direct usage questions or support issues to the mailing list:
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web:

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

 Title   : is_reference
 Usage   : $obj->is_reference()
 Function: sets and returns boolean values. 
           Unset values return false.
 Example : $obj->is_reference()
 Returns : boolean
 Args    : optional true of false value
 Title   : add_DBLink
 Usage   : $self->add_DBLink($ref)
 Function: adds a link object
 Example :
 Returns : 
 Args    :
 Title   : each_DBLink
 Usage   : foreach $ref ( $self->each_DBlink() )
 Function: gets an array of DBlink of objects
 Example :
 Returns : 
 Args    :

 Title   : repeat_unit
 Usage   : $obj->repeat_unit('ca');
            Sets and returns the sequence of the repeat_unit the
            allele is composed of.
 Example : 
 Returns : string
 Args    : string

 Title   : repeat_count
 Usage   : $obj->repeat_count();
            Sets and returns the number of repeat units in the allele.
 Example : 
 Returns : string
 Args    : string

 Title   : count
 Usage   : $obj->count();
            Sets and returns the number of times this allele was observed.
 Example : 
 Returns : string
 Args    : string

 Title   : frequency
 Usage   : $obj->frequency();
            Sets and returns the frequency of the allele in the observed
 Example : 
 Returns : string
 Args    : string
