<br>
Once you load a data set, executing the following script at the command line should add the events that you are looking for...<br>
<br>
%Get the latencies (data point indices) for all 'A' type events...<br>
<font face="Courier New">A_latencies=[EEG.event(find(strcmp('A',{EEG.event.type}))).latency];<br>
<br>
%for each A_latencies add a new event type '1' with a latency of </font><font face="Courier New"><font face="Courier New">(A_latencies(i)+1.5*EEG.srate)-1...<br>
</font>for i=1:length(A_latencies);<br>
n_events=length(EEG.event);<br>
EEG.event(n_events+1).type='1';<br>
EEG.event(n_events+1).latency=(A_latencies(i)+1.5*EEG.srate)-1;<br>
EEG.event(n_events+1).urevent=n_events+1;<br>
end<br>
<br>
%check for consistency and reorder the events chronologically...<br>
EEG=eeg_checkset(EEG,'eventconsistency');<br>

<div dir="ltr"><br>
</div>
<div dir="ltr">We have an EEG data with several events, which marked as 'A' and repeated every 5 sec. </div>
<div dir="ltr">what i am looking for is a way to add extra events to the data such as event '1' and appears 1.5 sec after event 'A'. </div>
