I’m integrating NiftyReg into an extension. (one of the goals is to get the computed transformation/deformation into Slicer) I registered two images with reg_f3d and saved the control point grid (to later get the deformation). reg_f3d -ref fixed.nii -flo moving.nii -res warped.nii -cpp controlPoin…

Due to using a wrong intent code, the ITK reader does not know that the vectors store spatial displacement and therefore the vectors are not converted to the correct coordinate system. BUG: Fix read/write of displacement field in NIFTI file format …

Deforming with NiftyReg is different than deforming in Slicer

The problem was a bit simpler - the displacement field from NiftiReg already had the correct shape, I only had to change the intent code
