Check for proper
alignment and defects
¥The Surface Volume and the
surfaces must be in perfect alignment.
HIf you have an
improper alignment, it should be addressed here.
åThis should not
happen for FreeSurfer and SureFit surfaces created in the standard
fashion.
HWatch for error
messages and warnings that come up in the shell as the surfaces are
read in. These messages should be screened once since they
do not change unless the surfaceÕs geometry or topology is
changed.
Hands-On
Note: Viewed without the volume underlay, it is extremely difficult to tell if surface models with no topological defects accurately represent the cortical surface.
