[Freesurfer] Volumes differ in geometry

Dear experts, Recently I run freesurfer longitudinal analysis (freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0), during the creation of the BASE, I get the following error "Volumes differ in geometry row=1 col=4 diff=4.745766(4.74577)".

Hi Sneha can you send us some snapshots? Or upload the entire subject and we will take a look. You can always erase cerebellum from brain.finalsurfs and rerun recon3 cheers Bruce On Wed, 28 Jan 2015, Sneha Pandya wrote: > Hi Team, > > Can anyone please share if they have been successful in
