[Insight-users] Image offset is giving bad pointer for large datasets (7Gb)

[Michael Jackson]

Basically you are stuck until ITK gets "Fixed" to use a long long int  
for the OffsetValueType. Because ITK is defining OffsetValueType as a  
"long int" you are going to be limited to an image size less than  
4294967295 bytes. The obvious workaround is to move to another 64 bit  
operating system that uses a different 64 bit model (LP64) for the  
compiler: Linux 64 or OS X both work as well as some others out there.
   Based on this thread it looks like the fix may be extremely time  
consuming to get accomplished. This is just my read of what is going on.
