Hi Kristina can you please post to the list so others can answer? If you add control points to the temporal WM where you are missing gm it should recover most if not all of it. Hippocampus is not neocortical and isn't supposed to be included. The surfaces are somewhat arbitrary there, and

Hi Sherryse you only need to register the anatomicals to the funtionals once, then sample the functional data onto the surface using mri_vol2surf. This will create a surface overlay that can be visualized on any of the surfaces for that subject (e.g. lh.white, lh.pial, lh.inflated) cheers
