Lead-DBS toolbox is used to segment globus pallidus internal, globus pallidus external, subthalamic nucleus and red nucleus, all of which are structures not automatically segmented by popular toolboxes such as FSL and Freesurfer. In addition, FSL's diffusion toolbox was used to generate probabilistic tractography between each segmented structure as well as compare the level of connectivity between each segmented structure.
