Dear D,

as a general remark that may also be relevant to some others here, I 
think you would have a better chance of getting replies to your posts if 
you revealed your real name. I for one rarely feel inclined to answer to 
anonymous posts.

You may also want to read the posting guide, there are a number of 
helpful suggestions that may help you to have more meaningful 
interactions: http://www.bioconductor.org/docs/postingGuide.html

Best wishes
   Wolfgang
