Dear Slicer community,

I have a problem using the DWIConvert option in 3D Slicer. The data I use are the once downloaded from the HCP webpage for the WashU subjects (latest Q13 acquisition). I am actually working on the subject 102109 (diffusion preprocessed HCP data).

I ran the process through the 3D Slicer gui and through the terminal (cli-modules of Slicer). When I tried without the “allowLossyConversion” option I kept getting errors about the output and the pixel size so I could not get my output. This is why I was forced to try it this way. This is the command I used in the end (the same result, at least visually speaking appeared with the gui too):

/Applications/Slicer.app/Contents/lib/Slicer-4.8/cli-modules/DWIConvert --conversionMode FSLToNrrd --inputVolume /Users/kyriakosdalamagkas/Downloads/102109\ 3/T1w/Diffusion/data.nii.gz --outputVolume dwi.nrrd --inputBValues /Users/kyriakosdalamagkas/Downloads/102109\ 3/T1w/Diffusion/bvals.bval --inputBVectors /Users/kyriakosdalamagkas/Downloads/102109\ 3/T1w/Diffusion/bvecs.bvec --outputDirectory /Users/kyriakosdalamagkas/Downloads/102109\ 3/T1w/Diffusion/ --smallGradientThreshold 0.2 --useBMatrixGradientDirections --allowLossyConversion

The output I got in the terminal was:

Wrote file: /Users/kyriakosdalamagkas/Downloads/102109 3/T1w/Diffusion//dwi.nrrd

The problem is that when I loaded the original nift file (I used the data.nii.gz with the dwi data from the HCP) the image was flipped compared to the image from the dwi.nrrd I got as an output. Also I think they are not registered to the same space anymore. Can you please guide me through? I am not very experienced with all these and can not figure it out. If you could please let me know what the problem is and what to do to resolve this and ensure the good quality of my data that would be great. I am basically trying to follow those two tutorials more or less: [https://www.slicer.org/w/images/8/86/DiffusionMRIanalysisTutorial\_Slicer4.5\_SoniaPujol.pdf](https://www.slicer.org/w/images/8/86/DiffusionMRIanalysisTutorial_Slicer4.5_SoniaPujol.pdf) and [http://dmri.slicer.org/tutorials/Slicer-4.8/FiberBundleSelectionAndScalarMeasurement.pdf](http://dmri.slicer.org/tutorials/Slicer-4.8/FiberBundleSelectionAndScalarMeasurement.pdf) to try out something for future work so your help would be much appreciated.

Thank you very much.

Best regards,  
Magda.

Please try a recent nightly (SlicerPreview) build. There have been many fixes to DWIConvert since 4.8.

Thank you so much Isaiah for the prompt response, I will definitely try that and get back to you. I hope it will make a difference. I will keep you posted regardless of the outcome so that you know what happened.

Hi Isaiah,

Getting back to you as I promised after trying the new nightly version of Slicer. Unfortunately the image is still flipped for some reason. I really have no idea why that happens and what I can do to alter the outcome. I can not be comfortable with the results I get due to that. Here is my new command and output in terminal again. I tried with the gui as well in 3D Slicer and I got the same thing. Again I was forced to use the “allowLossyConversion” to make it work somehow.
