<div>Hi Matt,</div><div> </div><div>I'm not sure if I understand your description completely, but I think that the problem you described is related to the settings of the input mask and terminate action. You probably have a sound or slide object for playing the sentence. I suspect that you added an input mask to this object to record the subject response. When the trigger-script is placed after this object, you will have a problem because the script will be exucuted after the button response in this case. Is this indeed what is happening?</div>
<div> </div><div>If this is the case, you could try to fix it by having a separate response object (such as a Text object) that is placed after the inline script. Instead of using the sleep function, you could set the duration of the sound-object to [delay]. The Sound 'Stop After' property should be set to No. However, the problem with this construction is that it is more difficult to make sure that the response object is displayed after the end of the audio track. (unless all sentences have the same duration). Perhaps the new Task Event mechanism of EPrime 2 will help out here: <a href="http://www.pstnet.com/support/kb.asp?TopicID=4803">http://www.pstnet.com/support/kb.asp?TopicID=4803</a> I haven't used this yet, but I think it should be possible to generate a delayed parallel port write operation.</div>

<span><span><span><span><span>Hello everyone,<br>
<br>
I'm running an experiment using triggers from Eprime to a BrainVision
equipment. I need Eprime to send a trigger according to the position of target-words along the sentence e.g. at 0, 5, or 11 seconds
after the beginning of the sentence. I tried used the following script:<br>
<br>
WritePort &H378, c.GetAttrib("trigger") 'identifies the item’ <br>
sleep c.GetAttrib ("delay") 'identifies the position of the target-word after the beginning of the sentence’ <br>
c.SetAttrib "CheckResponseTime", Clock.Read<br>
<br>
I defined two attributes: (i) trigger, as a code to identify the trigger
according to each sentence, and (ii) delay, as the time after the
beginning of the sentence the trigger should be sent to BrainAmp. After
listening each sentence, the subject has to answer a yes-no question to
check understanding. The problem is that the BrainVision cannot register
the trigger synchronized with the delay attribute, but only with the
time the subject hits the answer button.<br>
<br>
Does anyone have a solution or an alternative script for my experiment?<br>
<br>
Thanks in advance</span></span></span></span></span></blockquote><span class="HOEnZb"><font color="#888888">
