For short peptide sequences I would recommend that you try SCANPS by Goeff
Barton. You can submit your sequences at the following web site.


or alternatively you could try Edinburgh Biocomputing Systems´ very fast
implementation of the true Smith and Waterman algorithm called MPsrch at


All the best for your research.
