Bio::Tree::AlleleNode - A Node with Alleles attached


  use Bio::Tree::AlleleNode;


AlleleNodes are basic Bio::Tree::Nodes with the added ability to add Genotypes alleles as defined by the Bio::PopGen::IndividualI interface. Genotypes are defined by the Bio::PopGen::GenotypeI interface, you will probably want to use the Bio::PopGen::Genotype implementation.

This is implemented via containment to avoid multiple inheritance problems. Their is a Bio::PopGen::Individual object which handles the Bio::PopGen::IndividualI interface, and is accessible via the Bio::Tree::AlleleNode::individual method.


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.                  - 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.

This module was re-written to be a combination of Bio::PopGen::Individual and Bio::Tree::Node primarily for use in Bio::PopGen::Simulation::Coalescent simulations.

Bio::Tree::Node methods

Methods inherited from Bio::Tree::Node.


 Title   : add_Descendent
 Usage   : $node->add_Descendent($node);
 Function: Adds a descendent to a node
 Returns : number of current descendents for this node
 Args    : Bio::Node::NodeI
           boolean flag, true if you want to ignore the fact that you are
           adding a second node with the same unique id (typically memory 
           location reference in this implementation).  default is false and 
           will throw an error if you try and overwrite an existing node.


 Title   : each_Descendent($sortby)
 Usage   : my @nodes = $node->each_Descendent;
 Function: all the descendents for this Node (but not their descendents
                                              i.e. not a recursive fetchall)
 Returns : Array of Bio::Tree::NodeI objects
 Args    : $sortby [optional] "height", "creation" or coderef to be used
           to sort the order of children nodes.


 Title   : remove_Descendent
 Usage   : $node->remove_Descedent($node_foo);
 Function: Removes a specific node from being a Descendent of this node

 Args    : An array of Bio::Node::NodeI objects which have be previously
           passed to the add_Descendent call of this object.


 Title   : remove_all_Descendents
 Usage   : $node->remove_All_Descendents()
 Function: Cleanup the node's reference to descendents and reset
           their ancestor pointers to undef, if you don't have a reference
           to these objects after this call they will be cleaned up - so
           a get_nodes from the Tree object would be a safe thing to do first

"A name can be any string of printable characters except blanks, colons, semicolons, parentheses, and square brackets. Because you may want to include a blank in a name, it is assumed that an underscore character ("_") stands for a blank; any of these in a name will be converted to a blank when it is read in."



 Title   : internal_id
 Usage   : my $internalid = $node->internal_id
 Function: Returns the internal unique id for this Node
           (a monotonically increasing number for this in-memory implementation
