In this work we apply multivariate feature selection methods to construct a classifier that is able to differentiate among control sub- jects and OCD patients, with the purpose of bringing out regions of the brain that are relevant for the detection of the disease. Results show a dis- covery of regions that present great agreement with traditional methods used in OCD problems, but with the advantage of showing which ones are representative of control subjects or patients and providing cleaner and more accurate region maps.
