fnF1x4 - The F1x4 codon frequency model

This treats codon frequencies as a product of independent nucleotide frequencies. Since stop codons are removed from the codon alphabet, frequencies are renormalized so that the frequencies of non-stop codons sum to 1.0.


fnF1x4(Simplex baseFrequencies)


baseFrequencies : Simplex (pass by const reference)
The stationary frequencies of the nucleotides.
