Hi Victor, Being 2 separate atlases, this can happen. Maybe I should build a joint hipo/amygdala/thalamic atlas to prevent this from happening (this is why have the hippo and amygdala in the same atlas, in first place). Regarding this particular subject: if the overlap is the reflection of poor segmentation quality, then you can QC reject it. But if they look OK independently, it’s probably fine to use it. Cheers, /E

Hi,
I am visually quality checking the hippocampal and the thalamic subnuclei parcellations that Iglesias designed. I see that the hippocampal tail and the PuM (pulvinar) overlay with each other. What should I make of that? Is that a brain worth removing from analysis?
