Catching the culprit you cannot see
by the muttering of their subordinates
What actually drives a cancer is not DNA but protein — and protein activity is hard to measure directly. VIPER reads the state of the genes around a protein and works backwards to what that protein is doing right now, on top of the map of connections ARACNe drew.
Pictures and analogies instead of memorised formulas, and calculating it and checking it yourself instead of only reading. Python runs right inside this page. There is nothing to install.
How you'll learn
A regulon is the staff list under one boss, a signature is the commotion at the scene, NES is how sure you are of the name you have just given. You get a picture of the meaning before you memorise the formula.
Every piece of code has a run button. Take the answer you worked out by hand and have Python compute it and confirm it.
Every lesson comes with an illustration of the idea it teaches.
You assemble a regulon by hand, shuffle the ranks, walk aREA through one term at a time, and name the master regulator yourself.
