Bio::Map::LinkageMap - A representation of a genetic linkage map.
use Bio::Map::LinkageMap;
# create a new map
my $map = Bio::Map::LinkageMap->new(-name => 'Chads Superterriffic Map',
-type => 'Linkage',
-units=> 'cM');
# create the location of a marker for that map
my $position = Bio::Map::LinkagePosition->new( -positions => 1,
-distance => "22.3");
# create a marker and place it at that position
my $marker = Bio::Map::Marker::Microsatellite->new(
-name => 'SuuuperMarker',
-position => $position);
# place that marker on that map
$map->add_element($marker);
# done!
This object describes the basic functionality of a genetic linkage map in Bioperl. Each 'position' can have one or more markers that map some number of units from the markers at the previous position.
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.

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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : new
Usage : my $linkage_map = Bio::Map::LinkageMap->new();
Function: Builds a new Bio::Map::LinkageMap object
Returns : Bio::Map::LinkageMap
Args : -name => the name of the map (string) [optional]
-type => the type of this map (string, defaults to Linkage) [optional]
-species => species for this map (Bio::Species) [optional]
-units => the map units (string, defaults to cM) [optional]
-elements=> elements to initialize with
(arrayref of Bio::Map::MappableI objects) [optional]
-uid => Unique ID of this map
Title : length
Usage : my $length = $map->length();
Function: Retrieves the length of the map. In the case of a LinkageMap, the
length is the sum of all marker distances.
Returns : An integer representing the length of this LinkageMap. Will return
0 if length is not calculateable
Args : None.
Title : add_element($marker)
Usage : $map->add_element($marker)
Function: Add a Bio::Map::MappableI object to the Map
Returns : none
Args : Bio::Map::MappableI object
Notes : It is strongly recommended that you use a
Bio::Map::LinkagePosition as the position in any
Bio::Map::Mappable that you create to place on this
map. Using some other Bio::Map::Position might work but might
be unpredictable.
N.B. I've added Bio::Map::OrderedPosition which should achieve
similar things from LinkagePosition and will work for
RH markers too.
