Abstract

Model-based molecular phylogenetics plays an important role in comparisons of genomic data, and model selection is a key step in all such analyses. We present ModelFinder, a fast model-selection method that greatly improves the accuracy of phylogenetic estimates by incorporating a model of rate heterogeneity across sites not previously considered in this context and by allowing concurrent searches of model space and tree space.

Contributions

S.K., T.K.F.W. and L.S.J. conceived the method and executed a pilot study to assess the method's likely impact on model selection. B.Q.M. and T.K.F.W. implemented the method in IQ-TREE with contributions from S.K., L.S.J. and A.v.H. S.K., T.K.F.W., L.S.J. and B.Q.M. assessed the performance and accuracy of the method. S.K., T.K.F.W. and L.S.J. carried out the analyses of simulated and real data. L.S.J., S.K., T.K.F.W., B.Q.M. and A.v.H. wrote the paper.
