I agree with Andrew that data ordering/slicing (LAS/RAS etc.) should be a visualisation question and not a storage one. It would certainly simplify things, and no doubt save many people some grief, if there were one standard storage convention.

I am happy with the proposal, and willing to add support for NIfTI-2 in TractoR; but if Analyze backwards compatibility is to be broken, it does seem like an opportunity to consider some wider changes to the format.

All the best,
Jon
