Contrasting improvement of the dinucleotide GTR model over a nucleotide GTR process. nuGTR – for NF this is the nucleotide GTR model, for TF it is a comparable parameterization; diGTR – fully general time reversible dinucleotide model, with 48 parameters in the rate matrix; Δ ln L – is the difference in the cumulative ln L from the alternate model compared to the cumulative ln L for the nuGTR model.
