if it's only on one subject then it probably isn't an orientation problem. Checking it just means bringing it up in freeview and making sure that the directions that freeview shows (left/right, I/S, A/P) are actually the anatomical ones in the image.
Probably the orientation is right and the talairach just failed. There are instructions for checking and correcting the talairach.xfm on our wiki.

Hi Bruce,
How can I check if I have the correct orientation ? The initial image look as classical T1 weighted.
I have the problem only on one subject above all, so that sounds like an exception ?
Best regards,
Matthieu

Usually if you start from dicoms right from the scanner with a reasonable scan this isn't a problem so if it's happening frequently then it may be that something else is wrong.
