You don't need to do anything different. The only difference between scan lines and CellSpace is that for CellSpace, the lines do not need all the lines starting positions to align.
The best way to see what effect it has is to give it a try: you can change between the traditional approach and CellSpace by clicking the "From Selections" and "CellSpace" buttons in iolite's Imaging View.
Please let us know if you have any troubles.
