Hi,
I've not tested this, but the following should work. First you run
featregapply on all first-level .feat directories. Then run higher-level
analyses to combine across the 2 sessions for group 2 - you may need to
use the FE option, though the ME OLS option may work. Then I would have
thought that the combination across subjects should work ok?
Cheers.
