Hi David,
Thanks for your reply. I asked for this capability because I am trying
to perform a spherical registration. Many landmarks are defined as
starting and terminating at a certain distance from an anatomical
reference point. I thought that a tool, which allows the user to enter a
Oh! That's ridiculously easy. Those reference distances are in mm on
the inflated (except for the staring sylvian, which is relative to the
flat surface). You click one node on, say, the occipital pole; then you
click a border point along the calcarine you guesstimate is about 24mm
from the
Hi Donna,
That's exactly what I did (although, there are some details in your
example that I didn't understand well, see below). But, instead of keep
going forth and back selecting nodes and subtracting their coordinates
values (I had to do it quite often), I was wondering if there was not an
I already started having fun with Caret! ;-)
Thank you very much

better would be an accurate, automated border drawing utility.
Kidding aside, we recognize this is a highly desirable enhancement,
but
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
