Hello, I was Reading this article from the TCGA research group about multiform glioblastoma and there it is used microarray data of three platforms, one of them is Affymetrix Human Exon 1.0 ST Array, but this platform measure exons. So, I look for the supplementary data of the article in this website and I found that they transform the data ending with the expression of genes. Thus, my question is: How can be done that?
I'm very new in this stuff, so even when this is a silly question, the answer will help me a lot. Thanks in advance.
