[Mristudio-users] Mulitiple b-values

[Seongjin]

What I found while I was trying your recommendation, somehow DTI data
did not work with image sequence option "gradient by gradient".
When I selected the option with "slice-by-slice", I had a good 3D view.
Do you have any recommendation on selecting options on this?

Regards,

Seongjin
