Hi there,

We have a program called PyDesigner (https://pydesigner.readthedocs.io/en/lat...) that performs all the same pre-processing and also provides tensor calculations for diffusion and kurtosis along with their associated rotationally invariants (MD, FA, MK, etc). It is written entirely in Python and easily installed in a 'conda' environment. It could be a good solution as it automatically checks and runs the correct commands for the given data. It also can take in the DICOM folder as input. There is a tutorial video at the URL I posted above. There is also a GitHub forum for issues if you run into trouble (https://github.com/muscbridge/PyDesigner). The outputs are also compatible with MRTrix (orientation-wise) and FSL commands. 

Hope this helps, let us know. 

Best regards,
