[FieldTrip] Equivalent parts in an image and a mesh

[Schoffelen, J.M. (Jan Mathijs)]

Dear anonymous,

If you want "a regular 3D grid, based on a segmented MRI, restricted to grey matter”, why do you need the cortical surface reconstruction?

Best wishes,

JAN-MATHIJS

Thanks in advance.

Hi Dear All,
I apologize for my unclear question. I want to figure out where does each voxel of an image stand in a mesh after the mesh generation pipeline? I mean on which face and between which vertices? I hope I asked the correct form of a question this time.
Thanks for your attention.

Hi Angel Angel,

I don’t understand the question. Can you please have a look at the following before trying again?

Dear FieldTrip Experts,
How you find the corresponding part of an image in a mesh?
Looking forward to hearing from you.
