This method computes the sticks of the forest.
Arguments
- birth_threshold
The maximum birth time for the cells associated to the returned sticks (optional).
Value
The list of the forest sticks whose associated cells have
birth time smaller than or equal to birth_threshold. Each stick is
represented as the list of cell identifiers labelling the nodes in the
stick from the higher to the deeper in the forest.
Details
A crucial node of a forest is a root of the forest, a node whose parent belongs to a different species, or the most recent common ancestor of two crucial nodes.
A stick is a path of the forest in which the only crucial nodes are the first and the last one.
This method returns the list of the forest sticks. Each stick is represented by the sequence of cell identifiers labelling the nodes in the stick.
