Hi,
In FreeSurferColorLUT.txt (Freesurfer 5.1), there is a label for the inferior colliculus (7100), but this structure seems only to be labeled collectively with other brainstem structures (16) in aparc.a2009s+aseg. It appears from posts in the mail list that only a subset of the labels in FreeSurferColorLUT.txt make it into the automatic segmentation done by recon-all.
Any suggestions of how I could access lh and rh inferior colliculus labels for fsaverage, and then morph them to each subject's norm.mgz?
Thanks,
