weird? I'll need something more specific than that

Hi doug
Thanks very much. I see. When I add --tnullmin 2 --tnullmax 8, result
looks weird.

All time set is 1 TR except last three lines. Where am I wrong?
Here is my command: optseq2 --ntp 162 --tr 2 --psdwin 0 20 --ev ev1 2
41 --ev ev2 2 40 --nkeep 2 --o ex1 --nsearch 1000 --tnullmin 2
--tnullmax 8
Thanks.

Hi doug,
Thanks doug.
Here are two questions that I am not sure:
1, Each stimulus condition has three elements, i.e. cue fixation and
picture. However it is only picture element that will be analyzed.
The time window of picture will not influence the efficiency of sequence?
Not much
2, After stimulus presented(last 1.5s), subjects will response to the
picture in the specific time window. This time window followed the
stimulus, and it varied from 2.5s to ~8.5s. However, some trials was
not followed by NULL trial. That is to say, there is no time to
response after some trials.
You can create a minimum fixed amount of after the trial with --tnullmin

I don't think there is anything wrong with what you have. Is there a
problem? You could shorten it to something like 240sec or so.

Hi doug,
Th?anks doug.
In our experiment, there are 324s, and TR=2s, two kinds of stimulus.
Each one consisted of 3 components(cue 500ms + fixation 500ms +
picture 500ms), and will be presented with a interval of 1.5s. After
stimulus onset, followed by reaction time. One stimulus will repeat
41 times, the other 40 times.
Based on optseq2 --ntp 162 --tr 2 --psdwin 0 20 --ev ev1 2 40 --ev
ev2 2 40 --nkeep 2 --o ex2 --nsearch 1000, how should I modify to
get a efficient sequence, as I have no idea about NULL design.
Thanks again

I don't understand what you are trying to do. Can you elaborate?
There is no way to make optseq produce a sequence where two events
always occur in a certain order

Hi FS experts,
I try to design the schedule by optseq2. However it is beyond my
ability as our experiment has a little complicated.
Here is our goal:
two successive trials decide condition. For example, this is our
sequence:2 2 1 1 2 2 2 1 1 2 2 1 2 1 1 2 1 2 2 1 1 1 1 2 2 2 2 1 1 1 2 1 2 1 1 1 1 1 1 2 1 2 1 2 1 2 1 2 2 1 1 2 2 2 2 2 2 1 1 1 2 2 2 1 2 2 2 2 1 2 2 1 1 2 1 1 2 1 1 1 2
.22 and 11 is the same condition(this condition has 40 repeats); 12
and 21 is the same condition(this condition also has 40 repeats).
That is to say, there are two conditons in this run. 81 trials in
this run, and each trial has 1.5s intervels. And mean intertrial
intervals is 3.5s. Our TR is 2s.
According the efficiency about these two conditions, how could I
design the intertrial intervals to get a appropriate sequence?
I tried this:
optseq2 --ntp 203 --tr 2 --psdwin 0 20 --ev ev1 2 40 --ev ev2 2 40
--nkeep 2 --o ex2 --nsearch 1000
Although it echo a result, I know, it is not what I need, because
of every condition having two trials. So how I complete that?
Thanks.
All the best.
