Problem loading > 2GB volume

[Carlos Becker]

Hello, I am experiencing a problem that was already mentioned here:
http://groups.google.com/group/fiji-users/browse_thread/thread/ff62f38b3f2d723d/c6318d467f36e642
Is there a possible fix for this issue? I see it happening at the point
where Fiji tries to read pixel information beyond the offset 2^31. I have
just updated Fiji to the latest version and the problem is still there.
In my case the volume is not that big, but pixel type is RGB so the overall
size triplicates and this is what makes it unreadable by Fiji.

The volume was saved in a .tif file, unsigned char RGB, size 1500x1125x750.
Loading shows the "unexpected image offset" at slice 424 which happens to
be within the 2^31 boundary.

Thanks!

This bug is fixed in the ImageJ 1.46q daily build, which fixes a bug that caused both File>Open and File>Import>TIFF Virtual Stack to fail when opening >2GB TIFF stacks.
