If you've already run the Realignment module and have r* images, those
are already aligned to the mean EPI, so if you Coregister using the mean
EPI as the "Reference Image" and SPGR as the "Source Image", there is no
need to select "Other Images" -- the SPGR will be coregistered into the
space of the mean EPI, which is the same space that the r* EPI images
are already in from the realignment step.
