Hey Freesurfer,

 

I am new to Freesurfer. I wanting to use Freesurfer for measuring grey and white matter volumes in Multiple sclerosis. However I am wondering if there is a way to manually make a lesion mask for each individual and then use the mask to subtract the lesion volume from the white matter volume. We run recon we break it apart. So is there a certain recon set I can use to add the lesion mask to tell Freesurfer to subtract this volume from the white matter?

 

Many thanks,
