Hi SPM experts,
I want to specify the first-level model in SPM in my subjects. When I choose “specify 1st level” in SPM, I am requested to input the onset and duration for the condition(i.e. EV) (only one condition in this experiment). However, each of my subjects has an individual biological score and I want to “weigh” individual activation with this score. So, where can I input the score in SPM gui (parametric modulation?)?
(In FSL, I can choose 3 column format to define each condition. The first and second columns specify onset and duration, respectively, and I can input the scores in the third column.)
Thanks.
Mark
