Bio::Map::CytoMap - A Bio::MapI compliant map implementation handling cytogenic bands


    use Bio::Map::CytoMap;
    my $map = new Bio::Map::CytoMap(-name => 'human1',
                                      -species => $human);
    foreach my $marker ( @markers ) { # get a list of markers somewhere


This is the simple implementation of cytogenetic maps based on Bio::Map::MapI. It handles the essential storage of name, species, type, and units as well as in memory representation of the elements of a map.

For CytoMaps type is hard coded to be 'cytogeneticmap' and units are set to '' but can be set to something else.

Modified methods

All methods present in Bio::Map::SimpleMap are implemted by this class. Most of the methods are inherited from SimpleMap. The following methods have been modified to refelect the needs of cytogenetic maps.


 Title   : new
 Usage   : my $obj = new Bio::Map::CytoMap();
 Function: Builds a new Bio::Map::CytoMap object
 Returns : Bio::Map::CytoMap
 Args    : -name    => name of map (string)
           -species => species for this map (Bio::Species) [optional]
           -elements=> elements to initialize with
                       (arrayref of Bio::Map::MappableI objects) [optional]

           -uid     => Unique Id


 Title   : type
 Usage   : my $type = $map->type
 Function: Get hard-coded  Map type
 Returns : String coding map type
 Args    : 


 Title   : length
 Usage   : my $length = $map->length();
 Function: Retrieves the length of the map,
 Returns : undef since length is not calculatable for 
           cytogenetic maps
 Args    : none

Methods inherited from Bio::Map::SimpleMap


 Title   : species
 Usage   : my $species = $map->species;
 Function: Get/Set Species for a map
 Returns : Bio::Species object or string
 Args    : (optional) Bio::Species or string


 Title   : units
 Usage   : $map->units('cM');
 Function: Get/Set units for a map
 Returns : units for a map
 Args    : units for a map (string)


 Title   : name
 Usage   : my $name = $map->name
 Function: Get/Set Map name
 Returns : Map name
 Args    : (optional) string


 Title   : unique_id
 Usage   : my $id = $map->unique_id;
 Function: Get/Set the unique ID for this map
 Returns : a unique identifier
 Args    : [optional] new identifier to set


 Title   : each_element
 Usage   : my @elements = $map->each_element;
 Function: Retrieves all the elements in a map
 Returns : Array of Bio::Map::MappableI objects
 Args    : none
