Hi,

Yes, the TEST worked. Here are the three steps:

A) afni –ver output:
(base) Mac-Pro-de-Neurociencia:SUMA neurociencia$ afni -ver
Precompiled binary macos_10.12_local: Oct 2 2020 (Version AFNI_20.3.00 'Vespasian')

B) Surf Smooth response:

C) Commands used and response:
(base) Mac-Pro-de-Neurociencia:SUMA neurociencia$ 3dVol2Surf -spec std.141.Alejandro_rh.spec -surf_A std.141.rh.smoothwm.gii -surf_B std.141.rh.pial.gii -map_func ave -f_steps 15 -f_index voxels -sv Alejandro_SurfVol_Alnd_Exp+orig -grid_parent Alejandro_decon_Nopal.TENT.int.psc+orig -oob_value 0.0 -oob_index 0.0 -out_niml rh_Alejandro_decon_Nopal.TEMT.ave_.niml.dset
** surface name 'std.141.rh.smoothwm.gii' not found


This is previous step tan SurfSmooth. The thing is, the file std141.rh.smoothwm.gii is there in SUMA, but I can only advance from this step to SurfSmooth if I use my created mesh140.rh.smoothwm.asc. And then, in that step, SurfSmooth falls.

Thank you very much.
