[Freesurfer] field of value too small, wrap-around

Hello,

We have a relatively small FOV in our study because we mostly scan kids. Sometimes we scan adults with the same protocol, though, and after looking through the adults' reconned brains, I've noticed wrap-around on some brains. For one subject it's particularly bad; it affects aparc labels, where the very back of the brain gets labeled as orbitofrontal cortex. Is there a way to remedy this (other than increasing the FOV for subsequent subjects)? E.g. manually relabeling the affected regions?

I'm pretty new to FreeSurfer, so I apologize in advance if this questions is naive.

Thanks!
