Where do surface models come from ?
¥For surface based analysis:
HMust create surfaces for individual subjects
HPreSUMA:
åCollect, align and average high-quality, high-resolution anatomical data
íOn NIMHÕs 3T-1, 4 MPRAGE data sets will do
åCorrect image non-uniformity
íUsing AFNIÕs 3dUniformize or the N3 normalization tool [J.G. Sled et al. 98]
åCreate and correct surfaces
íUsing FreeSurfer, SureFit or BrainVoyager 
HCircumSUMA:
åAlign surface with experimental data
íUsing @SUMA_AlignToExperiment
åMap experimental volumetric data to surface
íUsing AFNI and SUMA
HPostSUMA:
åFame, Fortune and Fortitude for some, if not all, or none of you
