"ITK only supports orthonormal direction cosines" error when using antsRegistrationSyN.sh

[ramBrain]

Hi everyone,

I am trying to generate a transformation using antsRegistrationSyN.sh, but there seems to be an issue with one of the MRIs. Specifically, I get this error:

WARNING: In /usr/local/ANTs/build/ITKv5/Modules/IO/NIFTI/src/itkNiftiImageIO.cxx, line 1934
NiftiImageIO (0x560b169efbb0): ../defT1_bs.nii has unexpected scales in sform

By checking the header, the sform looks like this:

sto_xyz:1       0.995191 -0.009849 0.097461 -95.062607                            sto_xyz:2       0.047470 0.918793 -0.391875 -52.154037                            sto_xyz:3       -0.085687 0.394617 0.914842 -189.548813                           sto_xyz:4       0.000000 0.000000 0.000000 1.000000 

Any clue?

Thank you,
