You would set the voxel depth to 4.5um.  ImageJ does not distinguish
spacing and thickness.  The easiest way to import this stack into
TrakEM2 is to save it as a series of 2D images.

Side note: For 3D reconstruction, I was never happy to hear of thin
sections with extra-spacing.  This way, you are willingly undersampling
the axial dimension.  I.e. while you get excellent detail in the plane,
the continuity of your signal along z is anecdotal.  It's like scanning
a confocal image at very low resolution with a super small pinhole.
 Nobody would do that.

Best,
Stephan
