NAME

Bio::Map::Marker - An central map object representing a generic marker that can have multiple location in several maps.

CONTENTS

SYNOPSIS



  # get map objects somehow

  # a marker with complex localisation
  $o_usat = Bio::Map::Marker->new(-name=>Chad Super Marker 2,
                                  -positions => [ [$map1, $position1],
                                                  [$map1, $position2]
                                                ] );

  # The markers deal with Bio::Map::Position objects which can also
  # be explicitly created and passed on to markers as an array ref:
  $o_usat2 = Bio::Map::Marker->new(-name=>Chad Super Marker 3,
                                  -positions => [ $pos1,
                                                  $pos2
                                                ] );

  # a marker with unique position in a map
  $marker1 = Bio::Map::Marker->new(-name=>hypervariable1,
                                   -map => $map1,
                                   -position => 100
                                   );

  # another way of creating a marker with unique position in a map:
  $marker2 = Bio::Map::Marker->new(-name=>hypervariable2);
  $map1->add_element($marker2);
  $marker2->position(100);

  # position method is a short cut for get/setting unique positions
  # which overwrites previous values
  # to place a marker to other maps or to have multiple positions
  # for a map within the same map use add_position()

  $marker2->add_position(200);  # new position in the same map
  $marker2->add_position($map2,200); # new map

  # setting a map() in a marker or adding a marker into a map are
  # identical mathods. Both set the bidirectional connection which is
  # used by the marker to remember its latest, default map.

  # Regardes of how marker positions are created, they are stored and
  # returned as Bio::Map::PositionI objects:

  # unique position
  print $marker1->position->value, "\n";
  # several positions
  foreach $pos ($marker2->each_position($map1)) {
     print $pos->value, "\n";
  }



See Bio::Map::Position and Bio::Map::PositionI for more information.

DESCRIPTION

A Marker is a Bio::Map::Mappable with some properties particular to markers. It also offers a number of convienience methods to make dealing with map elements easier.

FEEDBACK

    Mailing Lists

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 list. Your participation is much appreciated.

    Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

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.

APPENDIX

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

    new



 Title   : new
 Usage   : my $marker = Bio::Map::Marker->new( -name => Whizzy marker,
                                                  -position => $position);
 Function: Builds a new Bio::Map::Marker object
 Returns : Bio::Map::Marker
 Args    :
           -name    => name of this microsatellite
                       [optional], string,default Unknown
           -default_map => the default map for this marker, a Bio::Map::MapI
           -position => map position for this marker, a Bio::Map::PositionI
           -positions => array ref of Bio::Map::PositionI objects

           position and positions can also take as values anything the
           corresponding methods can take



    default_map



 Title   : default_map
 Usage   : my $map = $marker->default_map();
 Function: Get/Set the default map for the marker.
 Returns : L<Bio::Map::MapI>
 Args    : [optional] new L<Bio::Map::MapI>



    map



 Title   : map
 Function: This is a synonym of the default_map() method

                   *** does not actually add this marker to the map! ***

 Status  : deprecated, will be removed in next version



    get_position_object



 Title   : get_position_class
 Usage   : my $position = $marker->get_position_object();
 Function: To get an object of the default Position class
           for this Marker. Subclasses should redefine this method.
           The Position returned needs to be a L<Bio::Map::PositionI> with
                   -element set to self.
 Returns : L<Bio::Map::PositionI>
 Args    : none for an empty PositionI object, optionally
           Bio::Map::MapI and value string to set the Positions -map and -value
           attributes.



    position



 Title   : position
 Usage   : my $position = $mappable->position();
                   $mappable->position($position);
 Function: Get/Set the Position of this Marker (where it is on which map),
           purging all other positions before setting.
 Returns : L<Bio::Map::PositionI>
 Args    : Bio::Map::PositionI
            OR
           Bio::Map::MapI AND
           scalar
            OR
           scalar, but only if the marker has a default map



    add_position



 Title   : add_position
 Usage   : $marker->add_position($position);
 Function: Add a Position to this marker
 Returns : n/a
 Args    : Bio::Map::PositionI
            OR
           Bio::Map::MapI AND
           scalar
            OR
           scalar, but only if the marker has a default map



    positions



 Title   : positions
 Usage   : $marker->positions([$pos1, $pos2, $pos3]);
 Function: Add multiple Bio::Map::PositionI to this marker
 Returns : n/a
 Args    : array ref of $map/value tuples or array ref of Bio::Map::PositionI



    in_map



 Title   : in_map
 Usage   : if ( $marker->in_map($map) ) {}
 Function: Tests if this marker is found on a specific map
 Returns : boolean
 Args    : a map unique id OR Bio::Map::MapI
