Hi Catarina

that is indeed strange. Can you upload one subject (the entire dir) and tell us the voxel coords of one of these points so we can take a look?
cheers

Hi freesurfer team,


I found in my datasets some scattered voxels with mislabeled hemisphere (see example figures in the
attached pdf).
I see the labeling error in aparc+aseg and aseg.mgz but aseg.auto and aseg.presurf appear to be
labeled correctly.

Also, I see nothing wrong with the surfaces where this is happening but several (if not all) of the
mislabeled voxels are right at the white surface.

I found this happening both with V6.0.0 and v6.0.1 for Linux (in both cases using the -hires flag).

This seems to happen to very few scattered voxels and I suppose it probably doesn't quite affect
volumes and thickness. But it might matter more if one is using the ROIs to e.g. average functional
data.
I'd like to know your view on whether it is important to fix this and the best to way to do it.


Thank you in advance,
Catarina
