Dear Johannes

Thanks for getting in touch. I don't think it is possible to save such
large files as a .tif file given the inherent limit on file size. I
think that is where the big tiff (.btf) format is preferable. As I said
in my message I have tried the most recent version of Bioformats but it
cannot open the file. Maybe the way CellR wites the .btf file is
incompatible. Which version of CellR are you using?

At the moment I am exporting the data using CellR to individual Z-stack
.tif files to restitch together.
