FASTA-pro file formatDescriptionList of protein sequences are commonly stored in data files using the FASTA format. This simple ASCII text format looks like this: >description line first protein SEQUENCEPROTEINHERE ANDHEREANDHEREAND HEREAND >description line second protein SECONDPROTEINSEQUENCEHERE ... This format has the advantage of being very easy to write and read. The description line is necessarily only one line long, which can limit its usefulness for recording detailed information.
A disadvantage of the FASTA format is that it is relatively slow to read with a computer. X! Tandem can also use a simple binary file version of an original FASTA file, which is about 6 times faster to read. The following illustration shows the structure of a FASTA-pro file:
