The description line (defline) or header/identifier line, which begins with '>', gives a name and/or a unique identifier for the sequence, and may also contain additional information. Users may often need to perform conversion between 'Sequential' and 'Interleaved' FASTA format to run different bioinformatic programs.

on multiple lines as in the above example, may also be 'sequential' when the full stretch is found on a single line. Nowadays, modern bioinformatic programs that rely on the FASTA format expect the sequence headers to be preceded by '>', and the actual sequence, while generally represented as 'interleaved', i.e. Thus, the examples above may as well be taken as a multisequence (i.e multi-FASTA) file if taken together. This does not imply a contradiction with the format as only the first line in a FASTA file may start with a ' ' or '>', hence forcing all subsequent sequences to start with a '>' in order to be taken as different ones (and further forcing the exclusive reservation of '>' for the sequence definition line).

It was also common to end the sequence with an '*' (asterisk) character (in analogy with use in PIR formatted sequences) and, for the same reason, to leave a blank line between the description and the sequence. Anything other than a valid character would be ignored (including spaces, tabulators, asterisks, etc.). Since the only comment used was the first, it quickly became used to hold a summary description of the sequence, often starting with a unique library accession number, and with time it has become commonplace to always use '>' for the first line and to not use ' ' comments (which would otherwise be ignored).ДЇollowing the initial line (used for a unique description of the sequence) was the actual sequence itself in standard Subsequent lines starting with a semicolon would be ignored by software. The first line in a FASTA file started either with a '>' (greater-than) symbol or, less frequently, a ' ' (semicolon) was taken as a comment. Also, the width of a standard printed page is 70 to 80 characters (depending on the font). Most people preferred the bigger font in 80-character modes and so it became the recommended fashion to use 80 characters or less (often 70) in FASTA lines. This probably was to allow for preallocation of fixed line sizes in software: at the time most users relied on Digital Equipment Corporation (DEC) VT220 (or compatible) terminals which could display 80 or 132 characters per line.

In the original format, a sequence was represented as a series of lines, each of which was no longer than 120 characters and usuallyДid not exceed 80 characters.
