I'm not 100% sure that I am answering your question. But, I will give
it a go.
In one of my studies, I ran three sets of the same kind experimental
stimuli (3 sessions x 28 events each=84 total events) for each of my 18
subjects (6 per group, 3 groups).
To analyze this data, I used a three level analysis:
First, I used Feat to analyze the session data (28 events per session),
for each session for each subject (3 x 18 = 54 analyses).
Second, I used Feat to analyze the subject data (3 sessions each).
Third, I used Feat to analyze the group data.
Hope that helps.
