¥Use 3dVol2Surf to map individual subject data onto each surface
ÐExample: Mapping functional data onto surface, with
thresholding
Ð 3dVol2Surf -spec
lh.spec \
Ð -sv SurfVol_AlndExp+orig \
Ð -grid_parent DataVol+orig \
Ð -cmask '-a DataVol+orig[3] -expr step(a-72)' \
Ð -map_func
ave \
Ð -oom_value -999.9 \
Ð -out_1D DataSurf.1D.dset
Ð Written by Rick Reynolds
¥-spec: SUMA spec file containing surface(s) to be used in
mapping. 3dVol2Surf uses one or two surfaces
for the mapping. Surfaces must have MappingRef = SAME
¥-sv: Surface Volume used to align surface to data
¥-grid_parent: AFNI volume containing data to be mapped.
DataVol contains 4 sub-bricks with the last
one being the threshold.
¥-cmask: Option for masking data in DataVol. Threshold value was 72
¥-map_func: Method for handling multiple voxel to one node
mapping
¥-oom_value -999.9 : Assign -999.9 to nodes that fall in
inactivated voxels
¥-out_1D: Output file
