Hi,
I have done coregister:estimate using the mean functional image (mean_func) as reference and anatomical scan (anat) as source. I saved the coregistration matrix M of this operation.
Prior to coregistration however I created a copy of anat (anat_copy), to which I applied the transformation matrix M (using Reorient by > Saved reorientation matrix). The aim was to be able to compare the results of the reorientation of anat_copy with the results from the coregistration: estimate with the anat image.
I was expecting anat and anat_copy to have the same orientation, since the reorientation matrix applied to anat_copy was derived from anat. However, the orientation is not the same, and the sform/qform matrices are also different between anat and anat_copy.
Clearly I'm misunderstanding how coregistration works, so I was hoping someone could help me out.
Best regards,
Sam
