no conversion from DWI to DTI

Hi Dr Xie. Thanks for trying the module! The module converts to nrrd and loads this DWI into Slicer. The module should not change any DICOM dictionary at all. Could you please explain in more detail what steps you used and where you saw this dictionary output? What do you mean by dictionary? (You do not need to load the DICOM into slicer. Just give the dcm2nii module the DICOM directory or folder that only contains the DWI.)
