C: Mapping FMRI Data Onto Surface
¥Interactive mapping is done by AFNI
HMapping is done by intersecting Mapping Reference
surface (the one sent to AFNI by SUMA)
with the overlay data volume.
åNodes inside a functional voxel receive that voxelÕs
color
¥Demo (continued):
HSwitch Overlay to DemoSubj_EccExpavir.DEL
HDefine Overlay with:
åOlay: Delay
åThr: Corr. Coef.
åPos. color mapping
å#20 color map
åSee Function
íYou should see the function on the surface model in
SUMA.
íThe colors are applied to all topologically related
surfaces
íNOTE: Only AFNI controller A sends function back to SUMA
åChange threshold in AFNI and watch change in SUMA
