I think you might need to switch these
dwi_2_mni_xfms = dwi_2_t1w["fwdtransforms"] + t1w_2_mni["fwdtransforms"]
to
dwi_2_mni_xfms = t1w_2_mni["fwdtransforms"] + dwi_2_t1w["fwdtransforms"]
Some more background on this convention here
Describe the bug I am trying to perform a DWI (FA) -> MNI registration via a DWI -> T1w -> MNI composite transform. After the composite transform is applied, the registration between the FA and MNI images is off by a few mm.
I was wondering if perhaps some of my parameters were off?
To Reproduce
I can send images if need be.
