PEFF

PEFF - PSI Extended Fasta Format

The PSI Extended Fasta Format (PEFF) is a proposed unified format for protein and nucleotide sequence databases to be used by sequence search engines and other associated tools (spectra library search tools, sequence alignment software, data repositories, etc). This format enables consistent extraction, display and processing of information such as protein/nucleotide sequence database entry identifier, description, taxonomy, etc. across software platforms.
