Hi - it's not clear what you're asking for - I think you're saying
that you want the average (across subjects) modelled response shape.
To get this simply run Featquery on the higher-level output (e.g. the
group mean of all subjects' first-level response strengths) with the
"%" option turned on. This single value then should be multiplied by
the normalised first-level regressor to tell you what the average
modelled response shape is.
Cheers, Steve.
