Discriminant analysis based on the normalized codon adaptation index (N-CAI) of the HEV ORFs in relation to all the hosts. All three HEV ORFs were analyzed together regardless of the genotype and the data were colored according to the ORF (a). Then, the ORF1s, 2 s and 3 s were analyzed separately and the data were colored according to the different genotypes (b, c and d, respectively)
