When doing a 12 parameter normalization, I get confused about the
parameters.
Clearly, the first 6 parameters are translations and rotations.
The last 6 are variously referred to as "scaling" or "zooms" or
"affine", depending on where you encounter them in the code or
documentation.
When a brain is linearly strectched to match a template, is that a zoom
or scaling or affine process?
Please clarify the meaning of these terms.
