I think this one thread might have disappeared (if not, I apologize for my impatience). Heidi

I just checked again in freeview and indeed they have the same index (e.g. CA1 has value 206 for left and also for right).

The color is not important. The question is whether they have a different index. Can you confirm that lh and rh have the same index?

Hi Doug,
Yes, for the aseg they are. But not for the hippocampal subfields: left and right have the same color coding. I am creating one segmentation, including left and right hippocampal subfields and aparc, for partial volume correction. Any idea how I can make the labels for the hippocampal subfields different (freesurfer version 6)?
Thanks Heidi

The indices should be different. Eg, 17 is left hippo, 53 is right hippo. If you click on them in freeview and different labels appear, then FS knows they are different

Hi.
Just one another related question: now that I was able to combine left and right hippocampal subfields with the aparc-aseg correctly, I noticed that the left and right hippocampal subfields have the same color labels and codes. What would be the best way to make sure that FreeSurfer understand that the left and right subfields (e.g. Left and right CA1) are different areas?
Thanks! Heidi
