Hi people,  
In short, I’d like to write a batch code to calculate Diffusion Tensors and FA for multiple DTI .nii data.  
I want to replicate steps in this tutorial [DTI-tutorial](https://www.slicer.org/w/images/3/35/DiffusionMRITutorial_UCSF2010_SoniaPujol.pdf) automatically. I will also need to convert all of my files(with associated bval and bvec) to nrrd files. I know how to do the steps using GUI, but couldn’t find a clue on how to pass those paramteres in a batch python code.  
Any Help?
