Turns out my lab’s preprocessing already included eddy, so I used their preprocessing pipeline, which does distortion, susceptibility, motion correction, and eddy. I then applied denoising and unringing as part of the MRTrix pipeline.
Both the denoising and Gibbs ringing removal operations are invalid subsequent to an image interpolation operation, so these can’t be run after eddy.
However, my FODs look very strange and non-anatomical after running dwi2fod:
Unfortunately the image is too low-resolution for me to assess.
