Table 1 Comparison of log likelihoods, AIC and BIC values among different partitioning schemes (from 1 to 13 partitions)

From: Phylogenetic relationships within the speciose family Characidae (Teleostei: Ostariophysi: Characiformes) based on multilocus analysis and extensive ingroup sampling

  1. For each type of analysis the following results are shown: total number of parameters; log likelihood calculated using RAxML (L ML ); AIC values; the difference in AIC values among model i and the best model (Δi = AICi - AICmin); BIC ML values.
  2. *1 partition = all dataset; 2 partitions = mitochondrial (16S + CytB) and nuclear (Myh6 + Rag1 + Rag2); 4 partitions A = 16S and 1st, 2nd, and 3rd codon position of protein coding genes; 4 partitions B = 16S + CytB and 1st, 2nd, and 3rd codon position of nuclear genes; 5 partitions = by each gene (16S + CytB + Myh6 + Rag1 + Rag2); 13 partitions = 16S + each codon position of each protein coding genes (1st, 2nd, and 3rd codon position of CytB; 1st, 2nd, and 3rd codon position of Myh6; 1st, 2nd, and 3rd codon position of Rag1; 1st, 2nd, and 3rd codon position of Rag2).
