-Stages describe the natural evolution of any cancer. You can find further information on the matter in
-[[http://www.cancer.gov/about-cancer/diagnosis-staging/staging/staging-fact-sheet]].
-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:
-  * Expression matrix: {{:kirc_demo_genes_vals_tumor.txt|}}
-  * Experimental design: {{:kirc_demo_ED_stages.txt|}}
-**3.3.-** Run the Differential signaling tool with the former files comparing stage I versus stage IV. Compare the results with those given in Exercise 3.1. Are there any differences? What do they mean?
+**3.2.-** Look at the results. If you have done Exercises 1 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.
