  1. "Best mrate" shows the best mutation rate. "Best %GC", "phase distribution (%)", and "error" are averages of 20 simulations for mutation correction at the best mutation rate. Error is measured as the χ2 value between the observed and predicted intron phase distributions. "σ" shows the standard deviation of error in 20 simulations. P-0, phase-0; P-1, phase-1; P-2, phase-2.
  2. * Not significant at the P < 0.05 level. All other comparisons were significant.
