Hello,

we want to estimate the orientation of the fibers in each voxel with constrained spherical deconvolution using Mrtrix. At the beginning, we would like to use files from AutoQc (e.g., *AutoQCed_DWI.nrrd), however, we could not convert  the NRRD data to Nifti using 3D Slicer.  We then choose to preprocess the origion data using mrtrix, which need to provide the phase encoding direction of these DWI datas. So would you please provide the phase encoding direction of these data for us. 

Thanks.
