Jed,
First, make sure you are mapping the functional volume to the 3D
fiducial surface.
Second, both the anatomical and functional volumes must be in the
same stereotaxic space. Load the anatomical and functional volumes
into Caret and verify that the functional data properly overlays the
anatomical data. In addition, if you load your 3D surface into
Caret, there is an option on the Overlay/Underlay-Volume Settings
page that allows the display of the 3D surface where it intersects
the displayed volume slice.

We have a flat map of an occipital lobe and are trying to map a

and it
does map the data set on but it appears to be off in the Anterior to
Posterior Direction.
The spgr used for the flatmap is from the same exam used to collect
the
functional dataset. Anything in particular I need to do to the
functional
dataset before trying to align to the flat map?
Thanks
