Hi, 2086--

I don't quite see what you are asking, but yes, you can select a region with the labeltable name.

For example, this should give you the "Brain-Stem"-labelled ROI from the dset as a binary mask in its own file:

3dcalc -a "aparc.a2009s+aseg_REN_gm.nii.gz<Brain-Stem>" -expr 'step(a)' -prefix output.nii.gz

--pt
