Dear FSL-users,
I'd like to create a single contrast between two paired 1st level
cope-images using a 2nd-level analysis:
Input: Group: EV1 EV2 EV3
1 1 1 0 0
2 1 -1 0 0
3 1 0 1 0
4 1 0 -1 0
5 1 0 0 1
6 1 0 0 -1
...
Since each EV only contains data from a single subject, would it still be
necessary to include group mean EVs, indicating which inputs belong together
(i.e. are derived from the same subject, are paired), for example:
...EV4 EV5 EV6...
1 0 0
1 0 0
0 1 0
0 1 0
0 0 1
0 0 1
...
Or would it suffice just to specify EVs1-3 (see above),
Thanks a lot,
Rutger Goekoop
