I have seen here Coregistering subjects: group template for mixed models? this comment:
you could indeed run the two procedures (surface and volume template alignments) described in the tutorial then create a mixed surface-volume source model from both, after pruning out the cortical grid points from the volume model, too avoid redundancy with the surface model.
I don't really understand what I could possibly do in this scenario. Correct me please if I am wrong. I really appreciate the help.
I understand I have to do surface also volume template alignment and then mix them in the anatomical model making a mixed surface model pruning out the repeated ROIs.
I don't know how to do this. If you could explain I could try to do it this way.
Anyways I can try with a volume model with AAL atlas. But I don't know how to obtain functional connectivity wiht that either.
I do the the anatomical volume model, then OpenMEEG realistic head model, then source modelling (dSPM) then connectivity coherence 2023 NxN. And then I obtain error saying index must not exceed 10638 bound array.
Am I doing somehting wrong ?
What difference would there be besides simplicity betweeen using mixed model or volume model?
