The idea is to get a genetic code from NCBI Taxonomy Homepage, or UNSW Embryology- NCBI-The Genetic Codes. All the codes from these pages can be extracted with makegcs.awk. An example of a single code is test. Remove the stuff before the " = ". Then use transposetxt.awk. Next, shift the nucleotides to lower case and substitute "u" for "t". Replace the fourth column (the starts) with a space. Then flesh out the code with ambiguity codes. Use blather2.awk to do so. It is far from perfect. Maybe we can do a Ruby version. We started with blather.rb, but that has a long way to go.
