Hi,
you can use the alternative reference image in the preprocessing tab / motion correction within Feat. Due to the fatsat the difference in registering unBETed vs. BETed EPIs to the structural is often small.
Cheers,
Andreas

Preferably, I would align run 2-n to run 1, and then have the same transformation to coregister to the structural scan. I know that in SPM and Brainvoyager, it is possible to do motion correction on run 2-n aligned to the first volume of run 1, but I was wondering how to do that in FSL.
