"We have a set-up with two groups of twenty subjects that have performed
four tasks separated in one run each. Is the attached set-up (with only
four subjects, to make it readable) correct for a 2nd level analysis? For
3rd level analysis we will compare the contrasts of the two groups."
We will be very grateful for any feedback, since we are quite uncertain
whether or not we did manage to setup this 2nd level analysis correctly.
