[FieldTrip] Antw: Scalp segmentation from an MRI (.nii or .fif)

[Gregor Volberg]

Dear Santosh,

for that purpose you might want to have a look at the NFT toolbox from SCCN, http://sccn.ucsd.edu/nft/ . It does high resolution segmentations for brain, csf,  scalp and skin surfaces. If you need the segmentation for computing forward solutions with BEM head models, then I would discourage a too fine resolution, though. It strongly increases the computational load.
Best regards, 
Gregor

Hello Everyone,
 
I'm very new to Fieldtrip and I need to perform scalp segmentation from an mri file(.nii or .fif). I'm working on a project where I need the scalp surface for surface matching, so I need the scalp surface with high resolution which clearly shows the facial features (nose, eyes, lips, chin). Any help/suggestions relating to this are much appreciated.
 
Thanks and Regards,
