Dear FSL community,
I have successfully run the 1st and 2nd levels stats, but have encountered these errors at the 3rd level. Other posts from users reporting 3rd level errors did not seem similar to this.
There are 2 groups, each with 5 contrasts/copes at the second level.
The EV setup is:
Group EV1 EV2
1 1 0
2 0 1
Contrasts:
1 -1
-1 1
The same error occurs on all the contrasts for the EVs:
