Full parametrization. Contains N free parameters, where N is equal to the size of the alphabet - 1. For codon models, N is the size of the alphabet - 1 - the number of stop codons, whose frequencies are set to 0.
For nucleotide sequences, theta is the GC content, theta1 is the proportion of A over A+T, and theta2 is the proportion of G over G+C.
@item Empirical(file=@{path@} [,col=@{int@}])
Read frequencies from a file. Each frequencies is set as plain column
in the file. If several columns are in the file, the number of the
column can be given with @{col@} argument (default: 1).
