Hi Bonnie,

Instead of telling 3dDeconvolve that you had stimuli via running waver
on a file that looks like:

0
1
1
0
1

on a 1.0 second grid, you can tell 3dDeconvolve to use a Gamma variate
basis function, GAM, and that the stimulus time were:

1.0 2.0 4.0

So if this were in a file called stim_times_fix.1D, then you could apply
them via:

-stim_times 1 stim_times_fix.1D GAM -stim_label 1 fix

That would be identical to running waver on the 0/1 file, and applying
it via '-stim_file 1 task-waver.1D'.

Note that the basic option is different, -stim_times vs. -stim_file.

One of the advantages is that the stimulus timings do not have to be
locked to the TR grid.
