Hi AFNI experts,
This might be a simplistic question, but I cannot figure out 1) how to check the output of 3dDWItoDT and 2) what to specifically look for.
Some insight would be awesome!
Thanks,
Steph

Hi, Steph-
There are several things to look at, such as where FA>0.2 (-> should match WM in ~healthy human adults). You can also look at DEC maps. Some description in the FATCAT_DEMO2 are provided here:
