The codon frequency table that GCG uses by default is just the table for ecoli:
ecohigh.cod (enteric bacterial highly-expressed genes, 7/19/83). This is the table
placed in the genrundata directory (gcg/gcgcore/data/rundata).
Other tables are placed in the genmoredata directory (celegans_high.cod,
celegans_low.cod, human_high.cod, etc.).

Try the map command with the -silent parameter.
