SIGNAL SCAN is a program that utilizes a transcription factor database to find potential transcription factor binding sites in DNA sequences. The program is now in its third version. The SIGNAL SCAN transcription factor database format has changed and the program output format has been improved. New features allow the user to update the SIGNAL SCAN database automatically, to retrieve original journal citations and to develop user signal databases. The program now uses an indexing algorithm, improving scanning speed by a factor of 3. SIGNAL SCAN is now network compatible and is available for IBM-compatible PC, Unix and VMS platforms.
