[ome-users] Bioformats only imports parts of .nd2 file

[Anna-Lena Merten]

Hi Romain,

thank you for your quick reply!

As you can see in the attached screenshot, there should be enough RAM 
available for ImageJ.

I tried using the virtual stack option (Plugins -> Bio-Formats -> 
Bio-Formats Importer, ticked the box 'Use virtual stack' in the dialog 
box), but the same problem occurs.

Best regards,

Anna-Lena

Even though the files are bigger than 7GB, ImageJ only indicates 2GB but does not respond with an error message (screenshots in appendix). There do not seem to be problems with files smaller than 2GB.
