Alignment with two anatomical scans


We have a participant who completed an anatomical, 2 epi runs and then unfortunately, had to be removed from the scanner. Shortly after, the participant went back in to complete the remaining 3 runs and completed another anatomical.

I was wondering whether there is a way to salvage and possibly use this data? Can I average the two anatomical scans and align all the functional runs to this average anatomical scan? Alternatively, can I align the remaining 3 runs to the first anatomical scan using the “-ginormous_move” or “-align_centers” option?

Thank you very much.
