**What it does**

"jModelTest is a new program for the statistical selection of models of nucleotide substitution based on “Phyml” (Guindon and Gascuel 2003. 
A simple, fast, and accurate algorithm to estimate large phylogenies by maximum likelihood. Syst Biol. 52:696–704.). It implements 5 
different selection strategies, including “hierarchical and dynamical likelihood ratio tests,” the “Akaike information criterion,” the 
“Bayesian information criterion,” and a “decision-theoretic performance-based” approach. This program also calculates the relative 
importance and model-averaged estimates of substitution parameters, including a model-averaged estimate of the phylogeny."
