Thanks for everyone's help on the list re my Haskell woes with the latest visualization effort. I've been making my code more generic for the last week, and I plan on releasing a visualization framework back to the community at some point. Gotta get approval from my boss before releasing code back to the wild, but here's an image of the draft of the visualization I've been working on: http://vizdata.renci.org/projects/jeff/ProteinViz/ProteinViz.png Basically, what you're seeing is 18,500 genes arranged in a full heirarchical clustering (the clustering technique uses a metric I'm unfamiliar with, and I got the dataset pre-packaged from the guy who's using it). The final visualization is fully interactive and runs fine under Linux, dies a miserable death under windows (runs out of RAM, and I can't figure out why, nor do I particularly care), and primarily runs on our 14 foot by 9 foot (4.5x3 metres for those of us in metric) linux display wall. The full program is about 800 linux of Haskell code using nothing but the standard library under GHC 6.8. Again, thanks for all your help! -- Jeff
