Hi Christine,

Your command looks okay, where the timing files should
contain the starting times of the 16 s events (and the
AM.txt file should also contain modulators). Check the
terminal output from 3dDeconvolve to verify that it seems
to be censoring the right number of TRs.

Regarding whether to put "Facts" in the baseline (i.e.
whether to add -stim_base 7), it is almost irrelevant.
The only effect of that (particularly since you use
-bout) is to the Full-F, which you probably do not care
about. The individual stats should not be affected.
The Full-F result would change from showing the effect
of both classes 7 and 8 to the effect of only class 8
(it would become the same a t-stat^2 for Detail).

Note that without -bout, putting "Facts" in the baseline
would mean that there would be no beta or stats output
for that class.

But to put it another way, unless you care about the
betas or stats for polort and/or motion, I would be
inclined to skip -bout and leave "Facts" in the main
model (in order to at least see the results, even if
they are not going to be reported).
