ClockstaR: Choosing the number of relaxed-clock models in molecular phylogenetic analysis

Abstract

Summary: Relaxed molecular clocks allow the phylogenetic estimation of evolutionary timescales even when substitution rates vary among branches. In analyses of large multigene datasets, it is often appropriate to use multiple relaxed-clock models to accommodate differing patterns of rate variation among genes. We present ClockstaR, a method for selecting the number of relaxed clocks for multigene datasets. © 2013 The Author 2013. Published by Oxford University Press. All rights reserved.
