Hello,
as I said, I would be surprised if you do not have two or three images.
Try the archives and play with the toolbox. The toolbox GUI looks
complex at first, but playing with the options will get you an idea of
how to proceed.
Cheers,
Marko

I would suggest you double check this (they may be in different folders). There is a lot of information on how to process them in the list's archives, and you can call the fieldmap toolbox from the menu, assessing the effects interactively. You will need to enter the exact values of your sequence, so you may want to talk to your MR physics people for guidance as to what to enter.
