Hi Mevlüt,
re the other models, please refer to their papers to better understand what they do.
Re our VTA model (which is still in beta version), it does matter which atlas you use to define the grey matter. Please also refer to the paper for specific questions first.
Some atlases lead to intersecting vertices in the meshing part and are thus not suited to define grey matter. The DISTAL Minimal atlas should work in most cases and gives a very precise definition of the grey matter of question – but of course this only works if the regions are the ones you’re interested in (they are STN, GP & RN).
Best, Andy
