Hi Kira,
I think I know what's wrong. If you open the original .CZI file in ZEN and
click on the info tab to the left of the image you should find the total
number of pixels in the X and Y axes. Write these down.
Next go back to the .tif file you created and open it in Fiji/ImageJ and
click on the Image<Properties tab.
Is the total number of pixels the same? I suspect it's reduced.
If the total number of pixels (in X and Y dimensions) is incorrect, the
macro probably converted the wrong resolution level from the .CZI pyramid
file.
Unfortunately I hard-coded this and have since discovered that ZEN varies
the number of resolution levels based on the size of the image. If you
just use Plugins<Bio-Formats<Bio-Formats Importer to open the one .CZI file
that converted incorrectly, a number of thumbnails should appear
representing the different resolution levels. Just open the one with the
most pixels (should be the top one) and save it as a .tif.
