So it dawned on me I could just use FSLSWAPDIM <input> -x y z and it seemed to do what I wanted
I first tried
-1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1
and tried to do ApplyXFM to apply the transformation-- I thought that would work, but when I get a blank output I decided to post my original matrix.
Is it because the reference of the 0,0,0 coordinate somehow doesn't get factored in or something fancy like that?
