reorient image

Hi,

When running DPARSF with the attached specifications, we are asked to manually reorient the image (see screenshot).

Is this something normal/correct, or can it be avoided?

If it is something that has to be done, what is the correct way to do it? Is the method explained in this example good enough? https://www.youtube.com/watch?v=AwNJAUKLhqY&feature=emb_title

Thanks,
