Hello,
I have a question about using mri_convert on diffusion *.dcm files. When extracted, the gradient table is different than that given by either MRIConvert (from the UCLA-LCNI webpage) or than dcm2nii of MRICron; NB: the latter give the *same* results. The differences in gradient are also not simply sign changes, unfortunately (though, there is that issue as well, since many x- and y- gradients of mri_convert are close to the others, but the z-gradient appears to be uniformly oppositely signed). This is coupled with the fact that often both the orientation is different (noted in previous entries), as well as the ORIGIN information being different.
Is there any comment about this? And any suggestions about what can be done to resolve these differences?
Thanks.
