FYI People found the 2002 talk of interest so I'll pass along the URLs for the updated 2003 talk. I gave this talk on Tuesday in San Diego at the O'Reilly Bioinformatics Technology Conference. 150 powerpoint slides in 90 minutes. whew. It's basically the same core/'best practices' slides from my 2002 talk with lots more case studies, pictures and other misc. content. Caution: may bore some of you to tears :) PDF is online at: http://bioteam.net/dag/Building-Bioclusters-Talk-2003.pdf HTML version is at: http://bioteam.net/dag/2003-ORA-Clustering-Talk/ Feedback appreciated Regards, Chris
