I am working on the gene expression analysis, I am using PCA and other clustering method to analyse the datasets but the results are not satisfactory. Is there any one to help me? Any kind of help is appreciated. If you have any suggestions please email me.
Am stuck for a while now, it would be great if anyone could guide me.

Have you tried posting questions on Research Gate?

Hello again treeoflife,

Yes, I have. Not lucky so far.

I'd suggest trying 'Cross Validated' which is a forum like Stack Exchange but for statistics.
