Artemis is a free genome viewer and annotation tool that allows visualization of sequence features and the results of analyses within the context of the sequence, and its six-frame translation. Artemis is written in Java, and is available for UNIX, GNU/Linux, BSD, Macintosh and MS Windows systems. It can read complete EMBL and GENBANK database entries or sequence in FASTA or raw format. Extra sequence features can be in EMBL, GENBANK or GFF format.
