Thanks a lot Peter!

While, just to be clear, if I transform a surface data to a volume data with the suma_MNI152* spec and surfVol file, the resulted volume data will be in standard space(in this case, MNI space), right? There is no need to do any warp or @auto_tlrc?

Following the above question, I did the transformation with MNI152 spec and surfVol file, the volume data I got is super big, as 3.3 GB for each hemi. There are 54 subbicks in the group analysis result, since I am using T1 from MNI152 as the grid parent, the volume data would be bigger, but I assume it wouldn't be such bigger, right? Would you suggest using the T1 as the grid parent?

See below my surf2vol code.

best,
Meng

foreach hemi(lh rh)

			3dSurf2Vol \
				-spec "$spath"/suma_MNI152_2009/std.141.MNI152_2009_"$hemi".spec \
				-surf_A smoothwm \
				-surf_B pial \
				-sv "$spath"/suma_MNI152_2009/MNI152_2009_SurfVol.nii \
				-grid_parent "$spath"/suma_MNI152_2009/T1.nii \
				-sdata "$hemi"_group_MVM.niml.dset \
				-datum float \
				-map_func max_abs \
				-f_steps 10 \
				-f_index voxels \
				-prefix ./"$hemi"_group_MVM
			
end
