[slicer-users] Problem using Resample Scalar/Vector/DWI

I tried to find where the problem was from and here is what I found:
-If I run the module outside of Slicer it works
-If I do it inside Slicer, I get the following error:
ERROR: In /home/hayes/Slicer3-release-gbt/Slicer3/Modules/CommandLineModule/vtkCommandLineModuleLogic.cxx,
line 1575
vtkCommandLineModuleLogic (0x157b6740): Diffusion Tensor Estimation
terminated with a fault.
When I save the transformed DWI on the disk, the vector [0 0 0] is
[NaN NaN NaN]. I am trying to figure out why.
