This is just a convenient place to put pictures
So in BO under /surfaces:
3dVol2surf -spec lh.spec -sv BR_SurfVol_Alnd_Exp+orig. -gridparent BRDelayr124+orig.'' -surf_A lh.smoothwm.asc -map_func mask -out_niml testret.niml.dset
Now to look at the pictures...
Useful Reminder: In the surface controller you can set the node where the cursor is located (for comparison between surfaces)
And now .. well..
