Hi Ziad,

Thanks for the input.
I'm still a bit confused.

I mean the 1D files output from 3dVol2Surf. I expect these files would be able to be loaded on diff. subject's std mesh surfaces with only slight variability; much like the ouput from 1deval would look loaded on each subj's std mesh surface.


I double checked my initial subj spec files and all have a spere.reg.
Here are the steps I have run (for each subj):
MapIcosahedron -spec subj_rh.spec -ld 141 -prefix subj_rh_ico_141

3dVol2Surf
-spec subj_rh_ico_141_std.spec
-surf_A subj_rh_ico_141_std.pial.asc
-surf_B subj_rh_ico_141_std.smoothwm.asc
-sv subj_NoSkull_SurfVol_Alnd_Exp+orig
-grid_parent subj_rh_func+orig
-map_func ave
-out_1D subj_rh_ico.1D.dset

The -sv file is the structural from my experimental scan that has been aligned to the subject's reconstructed surface.

Does anything look incorrect above? Am I missing a step?

Thanks
