[BioC] Common microarray clustering method

[Ilya Venger]

Hi,
I'm looking for a most commonly used microarray clustering method. The 
main problem is in deciding upon the appropriate amount of clusters to 
use in the clustering, both in the agglomerative and teh partitioning 
methods.
I know there are certain procedures such as MSS or v-fold cross 
validation, which I might run. This would allow me to compare 
clusterings resulting from incrementing the K (amount of clusters to use).
The main point is not only to find the best clustering algorithm, but a 
not less importantly, commonly used.

Thanks,
Ilya.
