Dear SPM-list,
I have specified a factorial design in the 1st-level analysis, namely
a 2x2x2x2-design. No complaints there. However, upon estimation I
receive the following error-message:
_________________________________

Error: spm_make_contrasts not written for 4-way ANOVAs !
Error running job: Output argument "Con" (and maybe others) not
assigned during call to "/Applications/spm5/spm_make_contrasts.m
(spm_make_contrasts)".

"run_est" at line 401.
_________________________________
The estimation seems to have worked fine, only the contrasts are just
not generated. Does anybody know what the problem is? Is it because
of the 4-way design? Or perhaps because there are 4 sessions and the
default setting in the GUI when defining a contrast is 'don't
replicate over sessions'? Thanks for any help!
Greetings, Roos
