Hi Johannes,

If you mean the file offsets are 64bit, you are presumably using the BigTIFF
format:
http://www.aperio.com/bigtiff/

Bio-Formats supports BigTIFF, so please give it a try if you have not
already:

If Bio-Formats cannot read your file, we would be interested in fixing the
problem. Let us know, and I will send you our FTP information off-list.
