Hi Bonnie,

If your purpose is to use the output file in 3dDeconvolve,
then I think the solution is to not use waver. 3dDeconvolve
can apply the GAM response model internall, and you can view
the ideal curve in the output xmat.x1D file. So it might be
easiest just to use stimulus times, in seconds, instead.

So, supposing that stim_1sec.1D is your 1 second TR stimulus
file, and supposing that it is 4 runs of 128 TRs (1 second,
each), then create 'times.1D' via:

make_stim_times.py -files stim_1sec.1D -nruns 4 -nt 128 \
-prefix times

Note that 3dDeconvolve does not needs stimluli to be TR-locked.
If you have a TR of 2.0, and stimuli at time 4.0, 17.0, 29.34,
that is okay.

How does that seem?
