Hello everyone,

I’ m reading a tutorial on 3DSlicer version 4.1 to learn how to use it. And it says to select the module “DWI to DTI Estimation”.  
But I didn’t find “DWI to DTI Estimation” in the module of my 3D slicer. I want to use the module. Did the name of the module change with the version?

Thanks.
