Hi

I am trying to import DTI data (connectome nifti format) into slicer with the DWI NiftiFSL to Nrrd Converter (Mac OS X 10.12.6, Slicer 4.9). It runs for 120s, but completes with errors*.

*Diffusion-weighted DICOM Import (DWIConvert) standard error:

libc++abi.dylib: terminating with uncaught exception of type itk::ExceptionObject: /Users/kitware/Dashboards/Nightly/Slicer-0-build/BRAINSTools/DWIConvert/DWIConvertLib.cxx:108:
itk::ERROR: Exception creating converter
itk::ExceptionObject (0x103e03ae8)
Location: "unknown"
File: /Users/kitware/Dashboards/Nightly/Slicer-0-build/BRAINSTools/DWIConvert/DWIConverter.cxx
Line: 220
Description: itk::ERROR: Mismatch between count of B Vectors (1) and B Values (143)

I already tried to reformat the bval and bvec files into columns (delimiter ‘,’ or ’ '), but it still doesn’t work.

Can you tell me, in what format the bval and bvec files have to be to work?

Thank you very much,
Best regards,

Lorenz
