It is possible that the various *.mexa64 files need to be recompiled for your
platform. I don't have access to one of those nice new 64 bit computers so I
can't be of much help, but if a 64 bit machine with 8Gbytes of RAM is having
memory problems, then some form of memory leak seems plausible.
Another thing to check is that voxel sizes, dimensions etc are all correct in
your images. If your images appear to have a field of view better measured
in light years than mm, then this would lead to memory problems.
