Hi Cristina,

The parameters you supplied are sufficient for DKI and DKE should work just fine with your dataset. However, DKE is now a legacy software that is no longer supported. Our lab has transitioned to a similar tool called PyDesigner, which we encourage all DKE users to consider using as well. It is a hands-off Python-based implementation of NYU's DESIGNER dMRI preprocessing pipeline designed to maximize signal-to-noise ratio. You can read about it further on the PyDesigner Github page here and in the PyDesigner documentation here.
