3.2 SWISS-PROT Field Definitions

The field codes found in a SWISS-PROT (or TrEMBL) sequence flat file are used to help arrange the information for human readabilty and machine-based parsing. There are several SWISS-PROT field codes found in a sequence flat file; they are represented by two-letter abbreviations. Table 3-1 summarizes the contents of each field code.
