hi-
i was hoping someone could help me set up an anova.
let me describe the experiment:
there are 2 groups with 12 subjects in each group.
each subject did 8 runs (4 run for condition C and 4 runs for
condition P, with 3 levels for each condition (ML/MH/SH)).
i ran the first-level analysis with 3EVs (ML/MH/SH) and then combined
the 4 runs of a single condition.
now i have 2 .gfeat directories for each subject: 1 for condition C
and one for condition P (each has 4 cope.feat dirs - ML, MH, SH,
MH-SH).
i want to look at the group differences across different conditions
e.g., groupA vs groupB, looking at ML-MH for condition C.
so i would have 48 inputs in my higher level analysis:
12 groupA cope1
12 groupA cope2
12 groupB cope1
12 groupB cope2
but i am not sure how to set up my EVs and contrasts.
also, what if i want to look at ML vs. (MH-SH)?
likewise, is it possible to look at group differences across conditions C+P?
thank you in advance!
