Hello everyone,

I have a DKI dataset from a 4.7T Varian Inova scanner that unfortunately does not export dicom files, but rather nifti files. The nifti files are accompanied by a bmatrix file (for use with ExploreDTI) and a gradient table file. I used MATLAB to convert the bmatrix back into bvecs and bvals. I then compared the gradient table file (organized in the bvecs format) with the bvecs file and they don't look alike! I have attached a sample of the two files from the same subject. Which one of these files should I use with DKE or any other DKI processing software package for that matter? (BTW, I know I have to use only one b0 image and only one set of gradient directions even if I have two non-zero b-values. Also, as far as I know, there is no way I can get dicom files from the scanner.)
