[Camino-users] Q-Ball probabilistic tractography

[Manuel Blesa Cábez]

Dear all,

I'm trying to obtain the probabilistic tractography with the Q-ball, I
follow the tutorial, but in the last step appears me some errors, I don't
know how to solve it.

track -inputmodel pico -pdf watson -numpds 3 -iterations 10 -seedfile
roi.nii -outputroot subject_roi_QBall10 -outputtracts oogl <
subject_QBallPDsWatsonPDFs.Bdouble
