As flatfiles represent the elementary unit of information within sequence databases and facilitate the interchange of information between these databases, it is important to understand what each individual field within the flatfile represents and what kinds of information can be found in varying parts of the record. While there are minor differences in flatfile formats, they can all be separated into three major parts: the header, containing information and descriptors pertaining to the entire record; the feature table, which provides relevant annotations to the sequence; and the sequence itself.
