Description
Computes the distance between two phylogenetic networks, based on their topologies. Three measures are currently implemented:
- Tree-based measure. (-m tree)
- Tripartition-based measure. (-m tri)
- Cluster-based measure. (-m cluster)
- Reduction-based measure (Nakhleh, L. (2010)). (-m luay)
The networks must be specified in the Rich Newick Format.
This program returns three numbers: the false negative rate (roughly, the trees/tripartitions/clusters found in the first network but not the second, divided by the number of trees/tripartitions/clusters in the first network), the false positive rate (roughly, the trees/tripartitions/clusters found in the second network but not the first, divided by the number of trees/tripartitions/clusters in the second network), and the average of the two rates (their sum divided by 2).
If reduction-based measure is used, this program returns only one number: the distance.
Usage
cmpnets network_ident1 network_ident2 -m [tree|tri|cluster|luay] [resultOutputFile]

network_ident1 | The name of the first network. | mandatory |
network_ident2 | The name of the second network. | mandatory |
-m [tree|tri|cluster|luay] | Characterization mode. One of tree, tri, cluster, or luay. | mandatory |
resultOutputFile | Optional file destination for command output. | optional |
