This will help:
caret_command -surface-to-volume
<input-coordinate-file-name>
<input-topology-file-name>
<input-metric-paint-or-shape-file-name>
<input-metric-paint-or-shape-column>
<output-volume-file-name>
[-inner inner-boundary]
[-outer outer-boundary]
[-step intersection-step]
Intersect a surface with a volume and assign the specified
column's data of the metric, paint, or shape file to the
volume.
The output volume file must exist and it must be in the
same stereotaxic space as the surface. A volume file may
be created by using the "-volume-create" or
"-volume-create-in-stereotaxic-space" commands.
The default inner boundary, outer boundar, and step size
are -1.5, 1.5, and 0.5 respectively.
The metric, paint, or shape file column is either the
number of the column, which starts at one, or the name of
the column. If a name contains spaces, it must be
enclosed in double quotes. Name has priority over number.
You'll also need something like these:
caret_command -volume-create 176 208 176 $PAINTVOL
caret_command -volume-set-origin $PAINTVOL $PAINTVOL -88.0 -123.0 -75.0
... but your dims and origin will depend on your atlas choice.
