Here's a codon usage table I just produced. The "Number" column is
the total number of that codon found in all the exons I processed,
"/1000" is the number of a codon per 1000 codons, and "Fraction" is
the fraction a particular codon is used for its encoded amino acid.

This table was built from 1817 exons (822163 codons) contained in the
seven completely sequenced S.c. chromosomes: I, II, III, V, VIII, IX,
and XI. Not all exons from these chromosomes were used. If a problem
was detected the exon was eliminated from this analysis. The GCG
CodonFrequency program was used to produce this table.
