I haven't seen such files myself, but that would be my guess as well.<br>
<br>
The larger issue is that the OpenSlide API doesn't provide a way to<br>
refer to more than one focal plane:<br>

<a href="https://github.com/openslide/openslide/issues/31" target="_blank">https://github.com/openslide/<u></u>openslide/issues/31</a><br>
<br>
so even if we added support to the driver, there would be no way to<br>
exercise it. This limitation affects several formats and will need to<br>
be addressed at some point.<br>

That would be very helpful.<br>
