My DICOM to DWI conversion works fine but number of scalars is zero in volume tab. So I am unable to increase DWI component. Can anyone help please?

That probably means that your dicom series wasn’t really a DWI. If you have more information to debug (like if you can share the data for testing) please start a new thread.
