Hi Johannes,
ImageJ supports reading 64-bit images as raw data (and converts these
to 32 bit).
If it is a one-time problem and you know the image size, you could
try to open it as raw data. You have to play with the offset. A
starting point might be Image size (in bytes) minus width*height*8;
then you have to vary the value until the image appears centered.
This won't work for all tiff images, only if the image data is one
big chunk.
Michael
