Hi Jerry,
what version of freesurfer are you using? And were you rerunning this subject, or was it the 1st time you ran it through? There was a bug with rerunning where the callosum would already be in the aseg and this would prevent us from finding the midline I think.
And yes, if you don't generate the aseg then you will have no subcortical volumes.
cheers, Bruce

Hello,
We ran into the following error during autorecon2 with one subject:
mri_fill: could not find any points where lh and rh wm are nbrs
It has been suggested to another user that the "-noaseg" flag be used. (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg06560.html) However, we would like to ask how this might affect the subsequent steps and how to take this into account in subsequent group analysis. Also, we would like to clarify if this would prevent the subcortical volumetric calculations.
Thanks!
