Thank you for your suggestions, The wb_command -cifti-seprate worked well.
I have another question which is related to my question regarding uniofrmly
spaced ROIs. I have saved the index of vertices in a text file which are
distanced uniformly from each other and I know these are the vetices on
You could try using wb_command -surface-geodesic-rois, it will draw
circular ROIs around vertices, as separate maps in a metric file. If you
want them all in one map, the -overlap-logic option to that command, and
the commands -metric-reduce, -metric-math and -metric-label-import may come
in
