The above example will output cell weights such as:

Cell wts for scale 1 -       0      0      0      0
Cell wts for scale 2 -      -0      0      0      0
Cell wts for scale 3 -    7302   9932   4074   5342    321    141
Cell wts for scale 1 -       0     -0      0      0
Cell wts for scale 2 -       0      0      0      0
Cell wts for scale 3 -    7302   9932   4074   5342    321    141
