Based on the similarity maps, portions of normal cortex appeared to be quite similar to FCDs, and FCDs on average did not appear to be more anomalous than some regions of normal cortex. We therefore first assessed whether FCD lesions in MRI+ patients would appear as global outliers in our feature space.  We therefore randomly selected 1000 patches from within manually labeled FCD lesions, and computed their distances from the center of the distribution. We compared these distances to those obtained from 1000 randomly selected patches of cortex from healthy volunteers, as well as from the previously identified outlier insular and motor cortex ROIs.
