If you were talking about geodesic distance (i.e., running along the
contour of the fiducial surface -- not as the crow flies through the
CSF/WM), then you could use the Surface: ROI feature for this purpose.
(First operation Geodesic Distance, and then threshold the resulting
metric at the desired distance.)
I'm not aware of something like that for 3D distances, but there's a
Make Sphere feature in Window: Script Builder. Worst case, you could
generate a sphere around the enclosing voxel and map that ROI volume to
the surface.

Hi,
In Caret5.5, is there a way of selecting a node and finding all (or
some) nodes that are at a given distance from it? I think I am looking
for something similar to what is described in section 2.17.2 (Foci
Data Searches) of the 'Caret Tutorial – the Basics'. But Section
2.17.2 regards only WebCaret. Does it exist something similar to
Caret5.5?
Thanks,
Mateus
