Yea, I've tried that before. It does not work very well. You can
proceed, but it will not be providing you with a very good correction.

Hi Freesurfer Experts,
I am trying to obtain coregister diffusion data b0 with T1.
One problem is that I do not have any means to correct for EPI
distortions.
Because of this, I am experimenting with DOF = 9 and DOF = 12. The
mincost for 12 was consistently the lowest compared to 6 and 9 across
my datasets [DOF 6 = 0.23, DOF 9 = 0.22, DOF 12 = 0.19]. However, it
is hard to tell that DOF 12 is the best just by looking at the
coregistered B0s overlaid on the brainmask.
Would it be fine to proceed with the DOF 12 option?
Thank you.
Best Wishes,
Shane
