Thank you for the bug report.  I assume that you see the same problem
with 5.0.0-beta1 (from http://www.openmicroscopy.org/site/products/ome5/bio-formats)?

What would you expect the overall image dimensions to be for CMU-1 (or
CMU-2 or CMU-3)?  My understanding for each of those is that there are
2x2 tiles, so 122880x122880 seems to make sense; if that's incorrect
though please let us know.

Regards,
-Melissa
