1. A computer-implemented method for mapping connectivity damage of a brain, the method comprising:
receiving a lesion segmentation mask for the brain;
receiving a tractography atlas, being an atlas built from diffusion MRI data of a plurality of healty subjects;
constructing a connectivity damage brain map by
(i) superimposing the lesion segmentation mask and a tractography atlas-based image; and
(ii) combining information from the lesion segmentation mask with information from the tractography atlas-based image;
wherein the tractography atlas-based image is an image obtained from the tractography atlas, and wherein the tractography atlas-based image and the lesion segmentation mask are registered to a common space.
