Thank you for the reply – you are indeed correct! The output looks fine.
As a follow up question – I want to investigate the structural connectivity between a seed roi (a lesion) and a common parcellation (rather than at the voxel level). To do this I have entered a the lesion as a seed roi amongst 246 other parcellation seeds and selected the ‘connectivity matrix’ option. This produces a 247 x 247 matrix which I assume denotes the number of streamlines between each of the regions I have entered into the seeds (246 parcellation rois and one lesion) – is that correct? (and if so – why does the diagonal contain values?)
Thanks again for the help – lead dbs is a fantastic tool!
