Hi Daniel,
Thank you for the explanation! Since I am using -closest_node and passing in a single input vector, I had assumed that's what it meant. However, I only passed in ~100 nodes, so it cannot be node number 342. I can only guess that means I'm doing something else incorrectly.
I followed @rickr 's suggestion here: Surf2VolCoord error - #8 by rickr
and using this restricted list of coordinates stored in '1_rh_cluster_xyz.1D', I'm running
Surf2VolCoord -i_vec 1_rh_cluster_xyz.1D 1_rh_cluster_xyz.1D -prefix 'closest' -closest_node '-21.0749 29.4453 27.8018'
As per Rick's comment about the mesh not being important, I used the same list as the mesh input. Even though I get a "valid" output from the command, the node index exceeds the input list and I get the following error:
Fatal Signal 11 (SIGSEGV) received
SUMA_SurfNorm
SUMA_PrepSO_GeomProp_GL
SUMA_Load_Surface_Object_eng
