Sorry, I don't quite understand yet.. Would the header be important as I am not using img / hdr ? Under what sort of circumstances would pix be favourable? I am using .nii after executing mri_convert to go from img/hdr to nii. I note that pix is used in other older threads too.

When the pixel  data are flipped, you are actually changing the way that
the data are stored on disk (while keeping the direction info in the
header constant).
