Hi Ola, this probably will not work. The tal coordinate is notoriously inaccurate in cortex. You are verylikely to totally miss the area you are looking for. A better way is to run the MNI template through recon-all, map your VBM result to the surface of that, then use mri_surf2surf to map the effect to each individual.
