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.

Doug --
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?

Doug Do you have any citations where people have done this before - it is relevant for a VBM + SBM analysis I am currently doing, Cheers Lena
