<p dir="ltr">Currently it's not possible to view the FODs in volume render mode - I couldn't think of a way of rendering such a massive amount of information as a volume render - it's hard enough to absorb all that information in single-slice mode... The only sensible way to do it would be to render the FODs on the clip planes, but then it doesn't really add much to the normal single-slice mode anyway...</p>
<p dir="ltr">And yes, of course it's possible to display the MRtrix3 generated FODs in the new viewer - although only in single-slice or ortho view. You can still display the MRtrix 0.2 FODs, but they will be subtly wrong since the definition of the SH basis has changed slightly. You really need to watch out for that, the difference is so subtle that I can't tell which is which by eye - you need to use the shbasis app for this. Now that I think about it, I might need to emphasise this more strongly on the wiki...</p>

Hi MRTrix community,<br>
<br>
a quick question. Is it possible to show the FODs with MRTrix3 in the Volume View?<br>
I guess with the MRTrix3 calculated CSD it works, but does it work with the MRTrix 0.2 calculated CSDs / FODs?<br>
<br>
