During my second level analyses, I have been receiving an error that says "Warning: possibly incorrect model: no constant term modeled (suggestion: add AllSubjects term to selected subject-effects list)." How do I fix this warning? I am not sure what I did incorrectly. I imported my data from SPM using the import tool and everything seemed to load properly (timing, conditions). Thus, I am not sure what went wrong. Please help me trouble shoot and let me know if this is an issue. I still am getting sensible results, so please let me know if I do not need to attend to this warning. Thank you.
