[FieldTrip] fieldtrip Digest, Vol 9, Issue 14

[Vema Krishnamurthy, Santosh]

Hello Gregor,

Thanks for the suggestions, I will give this a try. I'm not doing forward modeling with the high resolution surfaces. I'm trying to perform surface matching technique with scalp surface and the digitization data to do the co-registration of MEG and MRI.

Thanks and Regards,

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,

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
