Hi - I'll take a stab at this - Matthew can correct me if I get the
details wrong:
We've switched over the the sourceforge version of the NIFTI IO
library, and I suspect that's what's causing this. We'll fix this
ASAP, but in the meantime:
I believe that you can ignore this warning, or alternatively just
pass the data through fslmaths once and then it should go away.....:

Cheers, Steve.
