The number after "num TRs per stim (orig)" refers to the
number of (pre-censor) TRs where each regressor is non-zero.
Motion (baseline) is not included there, only the regressors
of interest. In the 7 TENT case that means there are
probably 21 values there, 7 for each stimulus class. And
the first and last from each class will be about half of
the size of the middle 5.
It does not differently affect your conditions (each set
of 7 values should be similar), the differential effect is
over regressors within each condition (1 small, 5 typical,
1 small (and repeat)).
