Hi there,

I've been having some overlapping problems related to this discussion thread, hoping you may have some insight.

The input nrrd (output from dcm2niix, and input to DTIPrep) is in left-posterior-superior orientation/space and of type (short).

The output QCed nrrd is in left-posterior-superior orientation and of type (unsigned short).

In order for Slicer's DWIConvert (to go from nrrd to nifti, using the NrrdToFsl option) to changed from unsigned short to short, requires the "allowLossyConversion" option (which is dangerous for potentially losing parts of the data). And I think this may be messing up my later stages of registration.

Is there a way to prevent DTIPrep output from having unsigned short type?

Thanks so much,
Micah
