Dear Daniel,

I have not yet any experience with FieldTrip, so I cannot reply on the
*.wrl issue.

But with respect to masks for the hand area, here is a tip: The Jerne
contains such localization masks. One important point is, that those
masks have a smooth transition between voxels inside the region (one)
and voxels outside the region (zero). If you need sharp transitions, you
may have to generate them yourself (apply a threshold on the voxel
values), or search somewhere else.

Best regards,
Tina Rasmussen.
