Hello,

I want to find the Euclidean distance between a node in one hemisphere and the location of every surface node in both hemispheres.

For example, for node 105 in the left hemisphere, I want to know how far this is from every node in the right hemisphere and left hemisphere of the pial surface. I am using this command:

SurfDist -I std.141.${hemisphere}.pial.gii -from_node 105L -input nodes.1D -Euclidean

Nodes.1D is a list of number [0,198812). When $hemisphere is set to "lh" vs. "rh", I get different output distances, but I am concerned that the function is ignoring the L in "from_node 105L" and just looking at the distances between node 105 to every other node within each hemisphere's surface. How can I find euclidean distances across the hemisphere?

Thanks!
