Filip,

I've no experience with ImageJ2 data structures and don't know about
their limits, but what does "x 1" mean in "33280 x 105216 x 1"?
Does it indicate a single image, i.e. no stack, or does it stand for a
binary-valued image?

If it is not a binary-valued image, what is its bit-depth?

Best

Herbie
