For example, this is used by Aligent's eArray software when saving microarray probes in a minimal tab delimited text file. See the page on FASTA format help for instructions on formatting FASTA sequences. Contact, document.write(''). The current version of the FASTA programs is version 36, which includes fasta36, ssearch36, fastx/y36, tfastx/y36, prss36, prfx36, lalign36 etc. An example sequence in FASTQ format is: @SEQUENCE_ID GTGGAAGTTCTTAGGGCATGGCAAAGAGTCAGAATTTGAC + FAFFADEDGDBGEGGB CGGHE>EEBA@@= For a detailed decription please see the Wikipedia entry .
