Hi,
I corrected for eddycurrents my b0+32 directions DTI, taking the 0th (b=0)
volume as a reference. I checked the ecclog, where I found 0...32 affine
transformations. I was surprised to see that the first one was not
(completely) a unity matrix:
0.999960 0.000000 0.000000 0.003120
0.000000 0.999960 -0.000232 -0.000654
0.000000 0.000232 0.999960 -0.044722
0.000000 0.000000 0.000000 1.00000
I am wondering why it is not unity matrix?
Thanks,
Martin
