    %% Count codons in a nucleotide sequence
% This example shows how to count codons in a nucleotide sequence.

%%
% Count the codons in a given nucleotide sequence.
codons = codoncount('AAACGTTA')

%%
% Count the codons in the second frame for the reverse complement of a
% given sequence.
r2codons = codoncount('AAACGTTA','Frame',2,'Reverse',true)

%%
% Create a heat map of the codons in a random nucleotide sequence and
% overlay a grid that groups the synonymous codons according to the
% standard genetic code.
a = randseq(1000);
codoncount(a,'Figure', true);
