n: order of substitution model;parms: number of free parameters (excluding equilibrium frequencies); acc: classification accuracy of substitution model alone; acc+MC: classification accuracy of combined substitution model and n-th order Markov chain applied to root taxon; MC: classification accuracy of Markov chain alone; time: training time in CPU-hours.
