A sample window during processing. The 4 bottom views are in the orientations shown in the icons just above them. The blue view is aritificial, with all circles moved to have the same (x,y) center. If the stacks are bigger than their box, they can be dragged around, or (of course) you can resize the window, and the boxes will also resize appropriately.
If we choose to "Show stack in Blob", then we might see the following:
This one is a partial with the center in slice 2. Note the heavy black line inthe stacks to indicate the bottom of the data volume.
This is a multiple, and the algorithm made the right guess. It's not clever enough to guess the slice number, though.
