Hello FreeSurfer Developers,

I'm attempting to compute  gray matter volume, but for some of my subjects I get the following error when I run the recon-all -all command:
 ERROR: inflating to sphere (rms error < 2.00)  final distance error

I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? Also, Ive attached the recon-all.log in case it's of any use.
