Since the move to Eigen, `mrinfo -transform` produces a 3x4 matrix text file. But `mrtransform -linear` expects a 4x4. We should probably be able to import the transformations we're exporting.\r\n\r\n2. I don't like how replacing the header transformation is done using `mrtransform -linear <text file> -replace`. I'd rather the `-replace` option be used independently of `-linear`. It would also then be possible for this option to take as its argument _either_ a matrix text file, _or_ a template image from which to take the header transform.\r\n\r\nFor reference, error is arising [here](https://github.com/MRtrix3/mrtrix3/blob/master/scripts/dwipreproc#L380)\r\n\r\nWant people's opinions on this, since `mrtransform` is usually pretty contentious."}}
