Hi Alfonso,

I use patient-specific ROIs (stroke lesions), and I want to compare ROIs from patients with good versus those with poor outcome. Patients can have multiple lesions/ROIs, however (e.g. if their stroke affected different parts of the same vascular territory). Is there a way to indicate that different ROIs come from the same patient, e.g. in the between-sources contrast? The reason for this is that ROI-networks from one patient will not be independent, and I think I should account for this to work with the correct degrees of freedom.

Thank you!
Eugenio
