Hi,
I want to use only the rotation matrix from my transformation to apply to DTI gradient directions. Are one of the outputs from "avscale" the rotation matrix, or how can I get it from those outputs? It seems like it must be in there somewhere without me having to recalculate it from the rotations in radians. Thanks!
Rotation & Translation Matrix:
0.999912 -0.002511 0.013051 -0.091762
0.002418 0.999972 0.007143 -2.479684
-0.013068 -0.007111 0.999889 1.818105
0.000000 0.000000 0.000000 1.000000
Rotation Angles (x,y,z) [rads] = 0.007144 -0.013051 -0.002511
Translations (x,y,z) [mm] = -0.091762 -2.479684 1.818105
Scales (x,y,z) = 1.000524 1.006485 1.000213
Skews (xy,xz,yz) = -0.001213 0.000272 0.002548
Average scaling = 1.00241
