Hi all,
I have a quick question regarding the PET-CT alignment. This question is regarding Moose v1.0. In 1.0, the model produces an image called MOOSE-unified-PET-CT-atlas.nii.gz. If I understand correctly, this is the fused label map. However, I would love a CT-registered to PET and a PET registered to CT. I believe that we can do that without any additional work because in the temp/labels folder, there is an affine matrix which I believe is the transformation matrix.

What software (ITK/ANTs) can be used to apply this transformation matrix to the image? The reason I ask this question is because the matrix is not in the usual ITK format.

Thanks @LalithShiyam you are awesome. I was going through the code to find out :)
