Hi DAIP,
  HGEOM run on a 1024x1024x63 cube dies on channel 63, line 950, as
follows:

We looked at a TVMOVIE of the cube & ran IMEAN on it; both worked without
any problems (apart from the IMEAN bug just reported), and certainly channel
63 itself both looks fine & gives a reasonable IMEAN.  There are no blanked
pixels in the input cube, and the header of the output file (which we checked
before the thing was destroyed, while HGEOM was running) looked fine:
