<br>
I believe you need to, but I recommend you to check it.<br>
After calculating a tensor field, perform some fiber tracking like<br>
corpus callosum and fornix. If there is any error in "flip", you can<br>
immediately tell.<br>
<br>
Also, I would suggest you to calculate "theory" image and "fitting<br>
error" images. If you make any mistake in gradient table (not the<br>
consistent sign flip but typo in a single (or multiple) table row),<br>
you can find it due to a consistent fitting error in one of the DWIs<br>
throughout the all slices.<br>
<br>
