PhyloNetworks: analysis for phylogenetic networks

Overview

PhyloNetworks is a Julia package with utilities to:

• read / write phylogenetic trees and networks, in (extended) Newick format. Networks are considered explicit: nodes represent ancestral species. They can be rooted or unrooted.
• plot networks (and trees)
• manipulate networks: re-root, prune taxa, remove hybrid edges, extract the major tree from a network, extract displayed networks / trees
• compare networks / trees with dissimilarity measures (Robinson-Foulds distance on trees)
• summarize samples of bootstrap networks (or trees) with edge and node support
• estimate species networks from multilocus data (see below)
• phylogenetic comparative methods for continuous trait evolution on species networks / trees

To get help, check

• the latest documentation
• the wiki for a step-by-step tutorial (June 2016) with background on networks
• the google group for common questions. Join the group to post/email your questions, or to receive information on new versions, bugs fixed, etc.

Maximum pseudolikelihood estimation of species network: SNaQ

SNaQ implements the statistical inference method in Solís-Lemus and Ané (2016). The procedure involves a numerical optimization of branch lengths and inheritance probabilities and a heuristic search in the space of phylogenetic networks.
