First, thanks for your prompt response. However, I could use a little clarification on your suggestions for option II. I have 15 subjects and 5 runs. Are you suggesting that I run temporal concatenation ICA with all subjects and all runs (e.g., inputs would be: subj1-run1; subj1-run2...subj1-run5; subj2-run1...etc.), with a subjects/sessions design matrix specifying which inputs belong to which subjects?
Thanks again,
Allison
