I'm not sure why coregistration with the T1 weighted image failed, whereas it
worked with the T2-weighted. I could make a few guesses, but my explanations
may not be so easy to follow. Manually re-positioning the images may help.
A search for "Display", "Check Reg" or "Reorient images" in the JISCmail
archives should throw up a few postings on this.
