I'm not sure what you are saying. Are you saying that the annot/surf
looks right but the seg in the volume looks wrong or that they both look
wrong?

External Email - Use Caution
Hi Freesurfer devs,
We have used mri_aparc2aseg to map the Stanford mpm/vpnl labels unto
the gray matter ribbon. We notice that when analyzing the resulting
mpm.vpnl+aseg.mgz that the regions/voxels of the mpm.vpnl+aseg.mgz
stretch out the corresponding voxels that the labels identify as the
mpm/vpnl. Can we reliably use the mpm.vpnl+aseg.mgz, and are the stats
created from that file, or from the annot file? We are asking because
we are using the mpm.vpnl+aseg.mgz as a mask for blood perfusion
measurements.
Thanks,
