Hi Martin,

I specified Input Dicom Data Directory and as a Output  DWI Volume file I just selected "DWI Volume file" . I can only choose between "none" or "Rename Currect Diffusion Weigted Image" or "Create new...", "Create new as..." or "Delete ..."

So I got an following errors:

Found CommandLine Module, target is /Applications/Slicer.app/Contents/lib/Slicer-4.5/cli-modules/DWIConvert
ModuleType: CommandLineModule
DWIConverter command line:

/Applications/Slicer.app/Contents/lib/Slicer-4.5/cli-modules/DWIConvert --conversionMode DicomToNrrd --outputVolume /var/folders/7q/y90nswcn65sfpj6wt7h47p3c0000gn/T/Slicer/JDJ_vtkMRMLDiffusionWeightedVolumeNodeB.nrrd --inputDicomDirectory /Users/Jacek/Desktop/Tracula/dti_jacekmanko --useBMatrixGradientDirections --outputDirectory /Users/Jacek/Desktop --gradientVectorFile / --smallGradientThreshold 0.2

and this one too

DWIConverter standard error:
