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('info@cbs.dtu.dk'). 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 .
