[cstrato]

Dear Nikul,

As Jim mentioned, you could use xps. You can find an example how to 
create the 'scheme' for MoGene 2.0 in ../xps/examples/script4schemes.R. 
However, first you would need to download the library and annotation 
files of MoGene 2.0 from the Affymetrix web-site.
(Furthermore, please read the README file how to install ROOT first.)

Best regards
Christian
