Hi Maxime

if you upload a gzipped tar file of the entire subject dir to our ftp site we will take a look. Please include voxel coordinates of the spots you think are inaccurate.

cheers

Hi Freesurfer Experts,

I tried to correct the midline with the information you provided me. Indeed, I 
tried to correct the aseg.presurf (Freesurfer v.6) using Freeview. Although 
parcelisation has changed, the midline has not changed. I launched several 
types of autorecon (-noaseg, -cp, -wm), but it didn't work. Do you have an idea?

Best,
Maxime

HI Maxime

check the aseg labels and make sure they are correct (and fix them if not). 
Probably a couple of left/right ventricle voxels are mislabeled

Hello FreeSurfer Developers,

I use Freesurfer 6 on macOS Sierra 10.12.6. In several subjects, I found 
midline cutting error, that
is the midline does not go through exactly the center of the brain in coronal 
cut. For example, the
midline is a little bit fuzzy and goes through an hemisphere than the other 
(see attachment). I've
searched in the mail list and ​I don't find the way to fix it. Does anyone have 
any idea to fix it?
Thank you,
Maxime Perron
