Dear freesurfer experts

 

working with MS patients I have several subjects with pial/white surface issues due to wm lesions. Following a suggestion I found in the mailing list using aseg to classify these areas as right /left lesion I get much better results for white surface. However the pial surface doesn't respect these changes and therefore cuts into the lesion area crossing white surface. Is there a way to define pial surface by the newly created white surface? Or anything else I could do to push pial surface outwards?

 

Greetings
