[ome-devel] extremely slow ome-tiff export for a stack over 1000 planes

[Melissa Linkert]

Hi Cail,

As mentioned in a similar thread on the ome-users list, we have recently
made several improvements to OME-TIFF export.  Could you please try
using the very latest trunk build of loci_tools.jar, and see if that
solves the problem?

Regards,
-Melissa
