Hi Jennine,
So that shows that lh_insula.1D.roi is appropriate to
use as input to 3dSurf2Vol directly. Do not strip the
node numbers via sed.
So run that command with the original roi file, and look
at the new lh_insula_roi+orig dataset in afni, and make
sure that it looks like your ROI. Be sure that you get rid
of the old lh_insula_roi+orig dataset first.
\rm lh_insula_roi+orig.*
3dSurf2Vol \
-spec AM-04V_lh_std.spec \
-sv AM-04VSUMA_SurfVol_Alnd_Exp+orig \
-surf_A wm \
-surf_B pial \
-sdata_1D lh_insula.1D.roi \
-f_steps 10 \
-grid_parent AM-04VSUMA_SurfVol_Alnd_Exp+orig \
-map_func ave \
-prefix lh_insula_roi
If this looks good in afni, then run your 3dVol2Surf
command again.
