RE: Is it possible to adjust the smooth parameters?
Trying to map voxels onto a mesh surface will always be tricky. In
particular, when you want to map voxels form a scan normalized to
MNI space to a very inflated mesh: in this case there is not a
one-to-one correspondence. I think the blurring helps reflect the
ambiguity of the transform. For accurate mapping you will want to
conduct the statistics directly on the vertices, you can use tools
like FreeSurfer or PALM that will help you with. In this case, each
individual's brain is warped to an inflated mesh and the statistics
are run in this space. Surfice is a visualization tool, not a
statistics tool, so these operations are handled by different
tools.
