Bio::Map::CytoMarker - An object representing a marker.
$o_usat = new Bio::Map::CytoMarker(-name=>'Chad Super Marker 2', -position => $pos);
This object handles markers with a positon in a cytogenetic map known. This marker will have a name and a position.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : get_position_class Usage : my $pos = $marker->get_position_object(); Function: To get an object of the default Position class for this Marker. Subclasses should redefine this method. The Position needs to be L<Bio::Map::PositionI>. Returns : L<Bio::Map::CytoPosition> Args : none
The numeric values for cutogeneic loctions go from the p tip of chromosome 1, down to the q tip and similarly throgh consecutive chromosomes, through X and end the the q tip of X. See Bio::Map::CytoPosition::cytorange for more details.
The numeric values for cytogenetic positions are ranges of type Bio::Range, so MarkerI type of operators (equals, less_than, greater_than) are not very meaningful, but they might be of some use combined with Bio::RangeI methods (overlaps, contains, equals, intersection, union). equals(), present in both interfaces is treated as a more precice RangeI method.
CytoMarker has a method get_chr which might turn out to be useful in this context.
The less_than and greater_than methods are implemented by comparing the end values of the range, so you better first check that markers do not overlap, or you get an opposite result than expected. The numerical values are not metric, so avarages are not meaningful.
Note: These methods always return a value. A false value (0) might mean that you have not set the position! Check those warnings.
Title : tuple Usage : ($me, $you) = $self->_tuple($compare) Function: Utility method to extract numbers and test for missing values. Returns : two ranges or tuple of -1 Args : Bio::Map::MappableI or Bio::Map::PositionI
Title : less_than Usage : if( $mappable->less_than($m2) ) ... Function: Tests if a position is less than another position Returns : boolean Args : Bio::Map::MappableI or Bio::Map::PositionI
Title : greater_than Usage : if( $mappable->greater_than($m2) ) ... Function: Tests if position is greater than another position Returns : boolean Args : Bio::Map::MappableI or Bio::Map::PositionI
Title : equals Usage : if( $mappable->equals($mapable2)) ... Function: Test if a position is equal to another position Returns : boolean Args : Bio::Map::MappableI or Bio::Map::PositionI
Title : overlaps Usage : if($r1->overlaps($r2)) { do stuff } Function : tests if $r2 overlaps $r1 Args : a range to test for overlap with Returns : true if the ranges overlap, false otherwise Inherited: Bio::RangeI
Title : contains Usage : if($r1->contains($r2) { do stuff } Function : tests wether $r1 totaly contains $r2 Args : a range to test for being contained Returns : true if the argument is totaly contained within this range Inherited: Bio::RangeI
Title : intersection Usage : ($start, $stop, $strand) = $r1->intersection($r2) Function : gives the range that is contained by both ranges Args : a range to compare this one to Returns : nothing if they do not overlap, or the range that they do overlap Inherited: Bio::RangeI::intersection
Title : union Usage : ($start, $stop, $strand) = $r1->union($r2); : ($start, $stop, $strand) = Bio::Range->union(@ranges); Function : finds the minimal range that contains all of the ranges Args : a range or list of ranges to find the union of Returns : the range containing all of the ranges Inherited: Bio::RangeI::union
Title : get_chr Usage : my $mychr = $marker->get_chr(); Function: Read only method for the chromosome string of the location. A shotrcut to $marker->position->chr(). Returns : chromosome value Args : [optional] new chromosome value
