[QUOTE=Francois;8897]Have you tried the simplest solution, which is to add the fiducial points (NAS,LPA,RPA) to your SEEG file?[/QUOTE]
Hi Francois,
we indeed tried the solution and it seems to give quite good alignment. I’ll try to quantify the displacements (if any) and let you know. It can be tricky (and prone to errors) the manual selection of exactly the same points using different viewer (our segmentation software is implemented as 3DSlicer plugin). Maybe a solution with automatically extracting from 500 points on the skull would give less problems. I’ll talk with software engineers and see if we can also test this solution.
BR,
