Later you can build more fancy ways to index matlab variables like the code you sent. So in other words, build your own baby loop that looks at each event, and makes a new time each time the event is 2.5.</span><br></div><div class="gmail_default" style="color:rgb(51,51,153)"><div class="gmail_default"><br></div><div class="gmail_default">1. Make a for loop that goes through each of the current events that are in the file</div><div class="gmail_default">2. If the current event in the loop matches the ones you are looking for (13), grab it's time in samples and/or seconds.</div><div class="gmail_default">3. Now add into a new variable this sample time you grabbed in step 2 plus 2.5 seconds </div><div class="gmail_default">4. At the end of the loop you should have a variable which contains a list of times, one time for each place you want one of your new "33" events.</div><div class="gmail_default">5. Then use the eeg_addnewevents function to simply add a "33" or "thirtythree" event label at each of the appropriate times. So here, all the new events are Added all at one time.</div><div class="gmail_default">***First try running this loop for just a few events and/or one file, and examine the resulting events in the eeglab file, before running the full loop on all events/</div><div><br></div><div>If you haven't taken the time yet, please be sure to also take a look at the 10 or 20 other messages on the lists about events as well, and try those solutions. Just google "eeglablist + events or eeglablist + adding/editing events". There are several from this year that list several options and examples. Regardless what option you pick, trust but be sure to Verify for Yourself.For example, see some examples below.</div><div><div class="gmail_default" style="color:rgb(34,34,34)"><font color="#333399"><a href="https://sccn.ucsd.edu/pipermail/eeglablist/2015/009240.html">https://sccn.ucsd.edu/pipermail/eeglablist/2015/009240.html</a></font><br></div><div class="gmail_default" style="color:rgb(34,34,34)"><font color="#333399"><a href="https://sccn.ucsd.edu/pipermail/eeglablist/2013/007031.html">https://sccn.ucsd.edu/pipermail/eeglablist/2013/007031.html</a><br></font></div><div class="gmail_default" style="color:rgb(34,34,34)"><font color="#333399"><a href="https://sccn.ucsd.edu/pipermail/eeglablist/2015/009265.html">https://sccn.ucsd.edu/pipermail/eeglablist/2015/009265.html</a></font></div></div><div><br></div><div><br></div><div>Things like talking to events do require a little matlab knowledge, but you can definitely do it if you know how to read function documentation, can find the correct variable fields in the EEG events structure, and can make basic matlab loops.<br></div></div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">What you probably want to use is eeg_addnewevents function, for which you can check past eeglablist notes and the documentation for that function (type help or doc + name of function at command line, you can also google the function).</div><div class="gmail_default" style="color:rgb(51,51,153)"><br></div><div class="gmail_default" style="color:rgb(51,51,153)">If you haven't yet, you should thoroughly look through the eeglab online tutorial and wiki regarding Event structure, talking to events, getting events, and Scripting.
