Hello,
I was wondering what orientation conventions are used when calculating the affine transformation matrix in register.dat. For an example, I'll use the data from subject 101 of the fsfast tutorial. According to mri_info, the functional volume is in LPS orientation, and the processed anatomical volume (T1.mgz) is in LIA orientation. Does the matrix in register.dat convert from the functional LPS orientation to the anatomical LIA orientation, or does the matrix assume these volumes are already transformed in some other way?
Thanks, Clark
