syco is a frame-specific gene finder that tries to recognize protein coding sequences by virtue of the similarity of their codon usage to a codon frequency table.
Here is a sample session with syco, requesting graphical output:
% syco -plot -cfile pae Synonymous codon usage Gribskov statistic plot Input sequence: embl:paamir Graph type [x11]:
It is essential to use the correct codon usage file for the species.
