If you're doing gene expression stuff, have you checked out the code 
available from biojava (http://www.biojava.org with API docs at 
http://www.sanger.ac.uk/Users/td2/biojava-docs/)? I know that they 
have some Suppor Vector Machine (SVM) code, which seems to be the most 
current "popular" method to cluster expression data. The paper in PNAS 
that I read on this also has a SVM implementation 
(http://www.cse.ucsc.edu/research/compbio/genex/genex.html), so they 
might be interesting to compare.

    Makes sense, especially when you're on a limited time frame. I'll 
be interested to hear how it works out.
