Hi Bernard-

This might be possible if we could get the image to map to XYZ.
By default, the box in the IDV is latitude, longitude, and altitude
and all data we handle has to have those mappings.  This is why
your generic Vis5D file does not display any vertical info - there
is no altitude coordinate (more on that later).  However, there
are also mappings to X, Y, and Z, so if you could create a custom
DataSource that would take an image and map it accordingly, then
that might work.  Alternatively, we might just need a new 
DisplayControl that would allow the user to change the mapping
on the fly.  I'll think of this some more.

I'm not sure you'd this is possible.  I'll discuss it with others.

What you would need to do is tag each image with the timestep that
would sync with the brain activity image.
