jMODELTEST: phylogenetic model averaging

© 2008-onwards David Posada

Current version is 0.1.1

jMODELTEST ijModelTest is a tool to carry out statistical selection of best-fit models of nucleotide substitution. It implements five different model selection strategies: hierarchical and dynamical likelihood ratio tests (hLRT and dLRT), Akaike and Bayesian information criteria (AIC and BIC), and a decision theory method (DT). It also provides estimates of model selection uncertainty, parameter importances and model-averaged parameter estimates, including model-averaged phylogenies. Please note that the DT weights are very gross

Operative systems
Although jModelTest it is optimized for MacOS X Intel, executables are provided to run the program under MacOS X PPC, Windows XP and Linux. In order to avoid potential problems during execution, the program folder and folders therein should be located under a path without spaces, although this is not always necessary.
