Hi, this is not an error as much as a warning that this feature has not been validated. Some context: the coregistration provides parameters describing translations, rotations, shears, and scalings. If the coordinate system of the image and the gradient directions is not the same, we risk rotating around the wrong axes. You can remove the error from the code, but you must then verify that the gradient table is rotated around the right axes. We have not had the resource to this for a wide set of data sets, and thus this feature is turned off by default.
