Do you mean from a annotation? If so, then you can use mri_annotation2label. This will dump all the annotations in to separate labels. If you mean to merge several labels together into one, use mri_mergelabels.

Note: the current version of mri_annotation2label requires a table (you can use aparc.ctab). It will also fail to create the last label. These are fixed in the current dev version, which I have copied to:

Dear all,

I'd like to create labels for certain structures based on their segmentation labels (e.g. a label containing all voxels in orbitofrontal cortex). Is there a way to automatize this? At the moment I'm using tkmedit to mark all voxels with the same segmentation label, then saving them as a label; that's a bit cumbersome... any hints?

Many thanks! johannes
