Dear MRTrix users and developers,
I’m trying to use mrtrix on phantoms generated by FiberFox. Unfortunetly, this program (part of MITK-Difussion) generates as output a *.dwi file. I tried to open it as text file and has something which makes me think is like an *.nrrd file. I’m trying to covnert it to a format MRTrix can deal with. DOes any of you have experience in those phantoms? Maybe someone know about another DWI simulator more friendly with MRTrix?
Thanks everybody 
Hi @mandorra,
I haven’t used FiberFox hands-on myself, but I’d be looking for ways to export it to a NIfTI… that’s a pretty common format, and MRtrix handles it very well out of the box. I’ve seen diffusion challenges/competitions based on FiberFox phantoms, where NIfTI files were supplied… so at least it has been done in some way.
Cheers,
Thijs
Hi,
Based on my little experience on FiberFox, there is a way to export data in Nifti format with MitkDiffusion:
In MitkDiffusion, open the *.dwi file that you have generated using FiberFox, right-click on your *.dwi file, choose ‘save’, and change the ‘files of type’ from ‘Diffusion Weighted Images’ into ‘Nifti’. That shall give you a *.nii file. From there, you can play the data with MRtrix.

Many thanks for your replies. I think this solve the issue.
