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. Mandatory qualifiers (bold if not always prompted):
