Hi Lars - This sounds like the subject was trying to climb out of the scanner: 3cm average translational motion and 24% of the slices in the series have drop-out. How do the images look?

Hi,
I don't have a lot of experience looking at dwi scans, but they don't seem crazy to me. I have attached screenshots of the dwi, FA, and brain_anat_mni images, and the gross anatomy looks fine to me. There are stripes in brain_anat_mni, which I would guess indicate motion..
Thank you!
sincerely yours,
