[MINC-users] minctracc (matlab and measure options)

[Andrew Janke]

Hi,

This output could be considered as "debug" from minctracc. I myself
have never used it but I suspect that it will have something to do
with plots of the simplex space for each of the indicated axes. (ie:
ry == rotation about the Y axis).

I would guess that there is probably only one person who knows for
sure though and that would be Louis Collins (the Author).
