Description

Computes the symmetric difference, also known as the Robinson-Foulds (RF) distance, between two trees. The trees do not need to be rooted. The trees must be specified in the Rich Newick Format. The tool reads in two trees. It outputs the number of False Negative edges, the number of False Positive edges, the number of internal edges in the experimental tree and finally the number of internal edges in the model tree.
