-Now we will try to understand how the Kidney cancer evolves by comparing the initial (I) with the final (IV) stages. We will use a subset of the former matrix, with a new experimental design, that you can download from the following links: +

What do they mean+**3.2.-** Look at the results. If you have done Exercises or 2, can you find any difference in the results of this dataset?
  
-**3.4.-** Look for some paths which are related with disease but not with its progression.
