It works! Thank you Peter and Rick!
I have one more question. well...this is something that i would like to get confirmation from you whether or not i am doing right thing.
I have a TLRC coordinate to create a ROI as a 1D file. (e.g. Intersection_tlrc.1D). The file contains x y z coordinates 40.931076 2.956589 55.040066 (placed on left hemisphere).
1. Find the closest node to ROI's coordinate:
SurfaceMetrics -closest_node Intersection_tlrc.1D -spec /Applications/freesurfer/subjects/suma_TT_N27/std.141.TT_N27_lh.spec -prefix Intersection
2. Expand nodes
ROIgrow -i /Applications/freesurfer/subjects/suma_TT_N27/std.141.lh.smoothwm.gii -roi_nodes Intersection.closest.1D.dset"[0]" -lim 3 -prefix ROImask_s01
3. Convert 1D file to .niml.dset file to visualize in SUMA
ConvertDset -o_niml -input ROImask_s01.1D -prefix ROImask_s01
Do these make sense to you or do you have any suggestions?
Thanks!
Taek
