In this page you will find different exercises for further practising in the use of the HiPathia Differentail Signaling tool. Try to answer the questions using the results given by HiPathia for each case.

To see how to use the application please visit the documentation of the differential signaling tool or the Differential Signaling worked example.

We will work with a Breast Cancer dataset from the repository The Cancer Genome Atlas. You can download the expression matrix and the experimental design from these links:

• Expression matrix: brca_genes_vals_bn.txt
• Experimental design: brca_normal-basal_ed.txt
