B: Aligning Surface w/ Experiment Data • Surface Volume is aligned to experiment’s anatomical volume with 3dvolreg Brain coverage and image types should be comparable, not necessarily identical • Functional data are assumed to be in register with experiment’s anatomical • Functional data are not interpolated • Demo: (close previous SUMA and AFNI sessions) – cd suma_demo/afni • DemoSubj_spgrax+orig (the experiment’s high-res. anatomical scan) • DemoSubj_EccExpavir+orig & DemoSubj_EccExpavir.DEL+orig (EPI anat. & func.) – @SUMA_AlignToExperiment DemoSubj_spgrsa+orig ../SurfData/SUMA/DemoSubj_SurfVol+orig • This script will use 3dvolreg to align the experiment’s anatomical volume to the Surface Volume. • The script will take care of resampling (with 3dresample) the experiment’s anatomical volume to match the Surface Volume if need be. • The output volume is named with the prefix of the Surface Volume with the suffix _Alnd_Exp (read Aligned to Experiment). – afni –niml & • We’re launching AFNI to make sure that SUMA/DemoSubj_SurfVol_Alnd_Exp+orig and DemoSubj_spgrsa+orig are well aligned. • Switch Anatomy to DemoSubj_SurfVol_Alnd_Exp+orig • Open New AFNI controller (B) • Switch Anatomy in B to DemoSubj_spgrsa+orig • Make sure controllers A and B are locked (XYZ Lock, i.e. NOT IJK Lock). Do this through Define Datamode Lock menu. • continue next slide… SSCC 4/25/03
