Hi Alena,
Randomizing that seems very challenging. The programs are not
written to have a variable list of durations (e.g. C can last
2 or 3 TRs, but no other duration). The other aspects are more
doable, chosing which sequence and how they are spaced.
You essentially have 4 event sets that last at least 7 TRs each.
Note that make_random_timing.py can do TR-locked timing (or not),
along with minimum and maximum ISI, if you want.
But how to choose from a list of durations is not clear (given
the current code). How necessary are those duration lists?
By the way, does this mean you will use duration modulation
with 3dDeconvolve? i.e. -stim_times_AM1 K XXX dmBLOCK(0)
If event A can last 1-3 TRs, you would really need to use
dmBLOCK(0) in particular (no other dmBLOCK would be quite
appropriate).
