Hi Russell,

Thanks a lot for your answer. I appreciate the time you've taken to look into this issue. The first thing I noticed is that I didn't change the image and gradient table orientation in the DKE_FT config file and thus I was actually getting the results in the wrong orientation, though I wasn't able to visually see it! This brings up my first question: How do you figure out the orientation of the image and the gradient table to be RAS and LPS, respectively (or any other orientation)? My second question is: How can I check the SNR in images and what is the SNR range for a normal image?

Also, I used the 'high' resolution option for the ODFs, so that may be a reason for the large file size as well. The .fib file is actually being partially saved. The strange thing about this is that the drive I'm using is formatted using the NTFS method, which unlike the FAT32 format does not have the 4GB file size limit, but only the first 4GBs of the .fib file is being saved. So, this leaves me suspecting that maybe this is a limit in DKE_FT or Matlab. Can you somehow check this?

If I change the 'save_odfs' to 0, is there another way to save the ODFs and visualize them separately later?

Thanks a lot,
Ehsan
