just visually. If we knew a way to automatically check it we would use
that to correct it :)

Hi Bruce,
Thank you for clarifying, this makes more sense, is there a way to check the
subcortical segmentation?
Thanks!

Hi Jasmin
the norm.mgz isn't a voxel labeling - it's an intensity volume.
We typically check the aseg.mgz display *over* the norm.mgz to
see if the labels make sense w.r.t. the intensities.
cheers

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
