Tensor flipping




Image tensorflipaxes If you have some problems tracking fibers with the DTI-track module, it might be because the estimated tensors are up side down because of some geometry problems. To solve this problem, you can flip the tensor field along the x,y,z axis in the Tensor viewer module. For that, open the problematic tensor field in the tensor module, then click on the axis to flip on the parameters panel (see Fig. 4.1). It may take a while to flip the tensors.




Once you have finished, you can save the resulting tensor field by clicking ``Save the tensor field''. You will be able to load it from the DTI-track module to track fibers with the right tensor field.
