FSL Developers/ Experts,

Just curious about the output of avscale, looks to me like theoutput "Rotation & Translation Matrix" from come from doing the Graham-Schmidt procedure on the columns of the original transformation matrix and the translation is just inherited from the initial map. Why is this viewed as the rotation part of the transformation matrix?

It's been a long time since I did too much linear algebra, so I'm probably missing something stupid. Any help would be great though.
