I am having difficulty converting DICOM files to nrrd using the DWIConvert module. The following command gives the output below: DWIConvert --inputDicomDirectory /path/to/dicom/files --outputVolume output.nrrd ======= DWI Convert Public Lib Ctest ========= Exception creating converter itk::Except…

I haven’t used DWIConvert with Bruker data, diffusion or otherwise, and the error message is not very helpful, unfortunately. But I do know there is currently no support for Bruker diffusion specifically in DWIConvert (this is a small animal magnet, correct?). If the non-diffusion volumes are “relat…

Hi atbauman, I am having the same issue as you. However, I could not figure out how you solved it from the selected solution. Would you mind elaborate a little bit? Thanks!

Hi @zjx1805 , I suppose calling this solved is not entirely accurate. I solved my issue of converting DICOM files to NRRD, though I ended up doing this without using the DWIConvert module. Instead I wrote a python script using Slicer’s python interpreter instead. The script basically uses the DICOM…

Thank you for the clarification!

Is the data in this question yours? I just evaluated the sample data @lassoan shared there, for a similar error. If so, then we should consolidate the threads and figure out next steps. See:
