Yes, smooth is not your problem.

IDL> a = randomu(s,100,100,100)
IDL> help, a
A FLOAT = Array[100, 100, 100]
IDL> help, smooth(a,3)
<Expression> FLOAT = Array[100, 100, 100]

Your problem is writing the data and/or reading the data. Without some code to look at, it's difficult to say.
Whatever, smooth() does not change the number of elements. At the edges "strange" things might happen, but no element is lost.

cheers, Helder
