Hi Claude,
Are you using workbench viewer? If so, you should be able to identify
particular thalamus or other subcortical MNI coordinates in the Volume tab
(brainordinate subcortical coordinates = MNI coordinates). You can also
split the thalamus structure out from subject¹s CIFTI file, if you want to
view/manipulate the data with other tools. The command would look
something like:
wb_command -ciftiseparate ${input_file}.dscalar.nii COLUMN -volume
THALAMUS ${extracted_thalamus_file}.nii
Best,
-Ely
