- --
- -- These are code and conversion tables for NCBI sequence codes
- -- ASN.1 for the sequences themselves are define in seq.asn
- --
- -- Seq-map-table and Seq-code-table REQUIRE that codes start with 0
- -- and increase continuously. So IUPAC codes, which are upper case
- -- letters will always have 65 0 cells before the codes begin. This
- -- allows all codes to do indexed lookups for things
- --
- -- Valid names for code tables are:
- -- IUPACna
- -- IUPACaa
- -- IUPACeaa
- -- IUPACaa3 3 letter amino acid codes : parallels IUPACeaa
- -- display only, not a data exchange type
- -- NCBI2na
- -- NCBI4na
- -- NCBI8na
- -- NCBI8aa
- -- NCBIstdaa
- -- probability types map to IUPAC types for display as characters
