[Mristudio-users] reading NRRD

[Syam Gadde]

Hello,

We have a user that's trying to use DTIStudio with our .nrrd files.

The error he's getting is:

   "NRRD-DWMRI file read error"

I have no idea why it doesn't like the file, but I'm hoping someone 
will.  I have included the header portion of the .nrrd file below.  It 
reads fine in some other tools (DTIPrep, for example).  Many thanks!
