Dear All,
My script runs like that. First in the beginning of the protocol:
question2.OnsetSignalEnabled = True
question2.OnsetSignalPort = &H378
question2.OffsetSignalEnabled= True
question2OffsetSignalPort = & H378
products2.OnsetSignalEnabled = True
products2.OnsetSignalPort = &H378
products2.OffsetSignalEnabled= True
products2OffsetSignalPort = & H378
question1.OnsetSignalEnabled = True
question1.OnsetSignalPort = &H378
question1.OffsetSignalEnabled= True
question1.OffsetSignalPort = & H378
products1.OnsetSignalEnabled = True
products1.OnsetSignalPort = &H378
products1.OffsetSignalEnabled= True
products1OffsetSignalPort = & H378
question1.OnsetSignalEnabled = True
question1.OnsetSignalPort = &H378
question1.OffsetSignalEnabled= True
question1.OffsetSignalPort = & H378
products3.OnsetSignalEnabled = True
products3.OnsetSignalPort = &H378
products3.OffsetSignalEnabled= True
products3.OffsetSignalPort = & H378
Before each condition (specific procedure)
I have a Inline like that
question2.OnsetSignalData ="2" and so on... for each of the question and products...
That works all fine! But I have to use a trigger for the responses of the stimuli. Whenever I insert
WritePort &H378,"11" or any other value,
I will be deeply grateful if you could help me out, as I tried various (hundreds of) diverse strategies to fix the problem and nothing seems to work!
Best,
Gabriel
I am a complete newbie in e-prime. A
philosopher by formation venturing myself in a postdoctoral fellowship
in neuroscience. And I an running against time to run an experiment
before my fellowship finishes.
I am having problems with sending triggers to the "Aquisition" machine.
In my protocol I have 3 procedures (conditions) that divide the big list into 3. I have a first general Inline to open the ports. And I have an Onset Inline for each of the questions and each of the stimuli that can after the question. All that works. I can manage to make the machines send triggers when the question 1,2 and 3 appears and then when the 1,2 and 3 stimuli appears. When I try to insert an InLine after the stimuli, the first trigger (the one that marks the onset of the question does not work anymore)
So my list is divided in 3 procedures (conditions) and each has the following structure

each product object, the first trigger (related to the question) stops
appearing in the aquisition machine. The Writeport command functions,
the products onset keeps working, but the question that comes in the
beginning of this condition stops appearing.Inline

Another ITI (Fication Cross with Jittered Values)

product (Stimulus/Image Display with fixed duration)
InLine - WritePort &H378,"11"

Gabriel,
I've read your post twice, but your description seems to have some contradictory information, so I'm a bit lost there...
Anyway, EP2 pro has a new method for generating triggers by using so called 'Task Events'. Task events offer a more elegant solution if your script has to create triggers when an input event occurs. Just have a look at these pages:

Gabriel,
First, what Paul said -- if you have EP2.0.10 or
later, you should look into using the new Task Events feature instead.
Second, this thread seems to stem from
https://groups.google.com/d/topic/e-prime/HZbe0baSMeY .
Third, a couple odditities in your inline code fragments. Your lines
question2.OnsetSignalData ="2"
and
WritePort &H378,"11"
just seem weird, are you sure that those do not read instead?
question2.OnsetSignalData 2
and
WritePort &H378, 11
? (Oh, and you should use Constants instead of
"magic numbers" in your code, but that is another matter.)
Now, for the advice. We have found that when we
have EP output a signal to an external device
(e.g., EEG), we then have to have EP reset the
output port to 0 before another output will
work. Remember, EP does *not* output *pulses*,
it merely sets the output to your data and then
leaves it there until you do something to change
it (I go over this in a lesson on my course). I
imagine that your Onset & OffsetSignal data
normally take care of setting the output, and
then later resetting it to 0. Your WritePort
does not. You would need to do another WritePort
to reset the output at some appropriate time, or
another OnsetSignal, etc. Task Events can make
it very nice to setup both the signal and the reset for any stimulus object.
Just a thought. Good luck.
