Viewing the group of surfaces• Controlling link between viewers:★ Open SUMA controller with ctrl+u or View->SUMA Controller★ SUMA controller crosshair locking options:➥ ‘-’: no locking➥ ‘i’: node index locking (i.e., topology based)➥ ‘c’: node coordinate locking (i.e., geometry based)★ SUMA controller view point locking➥ ‘v’: depress toggle button to link view point across viewers.➭ Surface rotation and translation in one viewer is reflectedin all linked viewersHands-On29 Oct 2009 SSCC/NIMH 30
Standardizing Surfaces For Group Analysis• Now that surfaces have been checked for quality, we willtransform them for group analysis• This step is the equivalent of standard-space normalization forvolume-based analysis.• In volume-based analysis:– goal is to have the same voxel spatial location correspond tothe same anatomical location in all subjects• In surface-based analysis– goal is to have the same node index correspond to the sameanatomical location in all subjects29 Oct 2009 SSCC/NIMH 31
