2.1 Example Flat Files

Sequence flat files are frequently used in many software tools. GenBank, DDBJ, and EMBL each have their own specific flat file format. Flat files from each of these databases are shown in the next several sections, and these examples are used to illustrate the field definitions and the feature table sections for each repository. The sequence from cyclin-dependent kinase-2 (CDK2) is used as the example for all of the sequence flat file entries and the fasta file.
