dear all:
I was wondering whether there is a simple way to do a rfx conjunction across
subjects for a single contrast (i.e., not a conjunction between groups or
conditions, but basically a conjunction across all the subjects in my sample).
For example: I have contrast images giving me the difference of condition A
against an implicitly modeled baseline for 25 subjects. Now I want to know
whether all those contrasts are above null.
I know that this can be set up using a fixed-effects model but is it also
possible on the second level?
Thanks in advance!
Claus
