Hi Romain
If you want to use several termination masks, you need to add them up into a single mask using fslmaths.
You cannot do that while seeding from the same masks, as the streamlines will not leave your seed masks by definition of a termination mask. If you want to seed from two rois while having them as termination, you need to run probtrackx twice.
Cheers,
Saad.
