Dear Freesurfer support,

I noticed in previous threads, people have inquired about how to check the
quality of the aseg.mgz segmentation using the norm.mgz as a reference.
When I did this, there were several mislabeled regions according to the
norm.mgz ie. voxels labeled as white matter on the norm.mgz but the
hippocampus on the aseg.mgz. Other times the accumbens was labeled as the
putamen or the pallidum as the amygdala. This was just in one participant,
other participants had several more discrepancies. Are these discrepancies
something that requires manual editing? Because I feel like I will have to
edit almost every voxel. Your suggestions would be greatly appreciated.

Thanks,
Jasmin
