Hi experts—I have some very low-contrast images from an older dataset and the Freesurfer segmentation completely misses the lower and posterior bits of the occipital lobe on many of the subjects (see attached images from an example subject).  What is the recommendation in this case?  Can I fix this with control points?  It’s a much more extensive failure than I’m used to seeing fixed with control points.

Thanks,

Jess
