[Mristudio-users] which is flip eigen vector

[Shao, Huiyan]

Dear DTIstudio experts,

I'm trying to do fiber tracking with DTIstudio. For the fiber tracking step, I am not sure which is our flip eigen vector. Below is our gradient table:

0:0.000000,0.000000,0.000000
1:0.539633,-0.488234,0.685874
2:0.453954,-0.517350,-0.725448
3:-0.709025,-0.702831,0.057543
4:0.693686,-0.259787,0.671797
5:0.248036,-0.662131,0.707149
6:0.019995,-0.691995,0.721626
7:-0.380197,-0.550811,0.743005

10:0.328108,-0.695394,0.639353
11:-0.258199,-0.691285,0.674877
12:-0.473483,-0.468429,0.745914
13:-0.668140,-0.275451,0.691170
14:0.735513,-0.465660,0.492119
15:0.500260,-0.698858,0.511212
16:-0.525531,-0.629740,0.572053
17:-0.676078,-0.457433,0.577645
18:0.702589,-0.711054,-0.027771
19:0.671769,-0.487322,-0.557893
20:-0.739823,-0.479095,-0.472367
21:-0.506710,-0.715022,-0.481652
22:0.702079,-0.711198,-0.035815
23:0.594285,-0.442036,-0.671885
24:0.698207,-0.711120,-0.082559
25:0.250124,-0.721895,-0.645218
26:-0.334558,-0.718487,-0.609793
27:-0.709479,-0.702971,0.049709
28:-0.746124,-0.301952,-0.593401
29:0.698770,-0.711214,-0.076781
30:-0.080715,-0.720450,-0.688794
31:-0.709677,-0.703022,0.046037
32:-0.748640,-0.010444,-0.662895

Can you decide which is our flip eigen vector?
