We would like to announce the availability of a new software
tool for the detection of consensus matches in DNA sequences
MatInspector is a program that uses a large library of predefined
matrix descriptions of transcription factor binding sites
to locate matches in nucleotide sequences of unlimited length.
It assigns a quality rating to matches and thus allows a quality-
based filtering and selection of matches.
(see Quandt, K., Frech, K., Karas, H., Wingender, E., Werner, T.:
MatInd and MatInspector - New fast and versatile tools for
detection of consensus matches in nucleotide sequence data
Nucleic Acids Research 23, pp. 4878-4884 (1995)).
The library of protein binding sites contains more than 200 entries
and is based on the TRANSFAC database (the new release 2.5 is
accessible via http://transfac.gbf-braunschweig.de).
The software and the library are available for UNIX, PC and MAC at
You can also use interactively MatInspector on the WWW at
Here the sequences to be analyzed can directly be submitted (copy and paste),
individual or groups of matrices from the library can be selected
and the resulting output can be saved for further processing.
