Cluster by GO

[Cheng, Jill]

For visual identification of gene clusters, Affymetrix offers a free web
tool for visualizing probe_sets based on GO annotations in the context of GO
graphic structure, go to http://www.affymetrix.com/analysis/index.affx  and
click on "GO analysis" tab, registration is needed but it's totally free.  
This tool is basically a GO-graph browser in the form of a heat map, it
takes a input probe_set list, and Go nodes are colored based on the counts
of hit, percentage of the sub-tree, or user specified parameters.  Thus gene
clusters may be identified visually.  The graph is also interactive,
clicking on a node brings up a tabulated executive summary of annotations
for the genes associated with that branch.
All feedbacks are welcomed!

I am wondering whether there are further activities in algorithms of 
gene/ptotein clustering by GO beside the existing tools listed in GO Tools 
in the Consortium page.

Thanks
