Daniel, We're repeating our paired-analysis of thickness measures between 5.1 and 5.2. In the meantime, to check for correctness, open the brain.finalsurfs.mgz file with the surfaces overlayed, and check the intensity value of the voxels which appear to be non-cortical 'black spaces', relative to neighboring gm voxels. ignore the aseg.mgz gm voxels, as those are not accurate (ie, dont load aseg.mgz when inspecting surfaces, or at least turn if off when inspecting gm regions....its still handy to see where hippocampus sits).
