Hi James,

If ss is indeed a 2D array, then setting it equal to savg(0,:,:)
should work (if you had done savg(0:0,:,:) this wouldn't work because
this is a 3D array with "1" as the leftmost dimension).

Can you email me the following:

    printVarSummary(savg)
    printVarSummary(ss)

This might give some more clues as to what's going on. It's also
possible the error message is referring to a different line number.
