Hmmm, not sure. can you send the full terminal output?

Hi Doug,
After resampling the aparc annotation into the functional native space, the LUT
values no longer correspond to the correct regions. A screenshot is attached
here: http://i.imgur.com/HNIgrKI.png
The values for the labels range from 1 - 35 only.
The command is mri_label2vol --annot $i/label/rh.aparc.annot --temp
${i}_medn.nii --reg $i/fmri/fmri_t1_mricoreg.dat --fillthresh 0.5 --hemi rh
--subject $i --proj frac 0 .1 1 --o ${i}.rh.aparc.in.func.nii
The goal is to apply the annotation and extract the regional fMRI data (4D)
using this 3D volume parcellation. Could we achieve that by using these steps?
Thanks.
Best Wishes,
Elijah

You can try mri_concat seg1.nii.gz seg2.nii.gz --sum --o seg.nii.gz
This will work if there are no overlapping voxels. If there are, you'll have to
do something like
mri_mask seg1.nii.gz seg2.nii.gz seg1-masked.nii.gz
then use the masked in the mri_concat command

Hi Freesurfer Team,
I am trying to resample the aparc annotation into functional space using
mri_label2vol. It works fine and the script produced the segmentation for each
hemisphere. Is there a way to merge both the left and right volumes together?
Thanks for your help.
Best Wishes,
Elijah
