I'm not sure what you have against the full list of labels if you don't use them, but assuming you want to make a "junior" atlas, you can do it with "@Atlasize -skip_novoxels". The skip_novoxels just uses 3dBrickstat to find ROIs that have 0 voxels and leaves them. You have to provide a list of indices and labels. We have that list of course, but you can regenerate it.
