Hi Scott, no there is not another space I would recommend. The cortical surfaces across subjects don't line up at all with a 12DOF transform. If you look at your activation in the volume along with surface lines, you may see that your surfaces intersect some of the activation but not others. I guess if the surface is showing your important activation, then it's probably ok. I've seen people do this before.

After you've gone into MNI space with all of your subjects, then visualizing the results on the surface are of questionable value.
All of our first-level and second-level statistical maps in MNI space and we wish to overlay them onto fsaverage, is there another space I could map these spmT images into that when overlayed would be more reliable/publication worthy? If this wouldn't work, what would you suggest?
