FindTensorPermutation[tensor,vox]

performs tractography for all tensor permutations and gives back the one that has the longest tracts.

FindTensorPermutation[tensor,vox,{par,{min,max}}]

same but with additional stopping criteria par, where tracts are only generated between values of par min and max.

FindTensorPermutation[tensor,vox,{{par,{min,max}},..}]

same but with multiple additional stopping criteria. Output = {permutations, flips, plot}
