That does look odd for an FA map… May I ask whether these were acquired on a Phillips system? If so, this could be related to [this issue](https://community.mrtrix.org/t/dwipreproc-eddy-error/913/13) – which I note we are not always able to detect correctly. If you can post the full output of `mrinfo <input image> -dwgrad`, we might be able to spot the issue if that’s what it is…
