Our study is a repeated-measures design (each subject had two
sessions). Event types (conditions or different kinds of stimuli) were
ordered differently for all subjects (all subjects have different
onset times for each event type). Ultimately, we would like to compare
brain activations among different event types (1) WITHIN each session
and (2) AMONG the two sessions.
Am I to create a design matrix(spm.mat file) for each subject (in each session) or
two design matrices (for two sessions) for all subjects?
I hope my question is clear
