<div dir="ltr">Hi Elisa,<div><br></div><div>I'm not an expert, but let me try to help you. It is a bit difficult to know how to adapt this script to your data without knowing what your data looks like.</div><div>Maybe you have already done so, but I think to make scripting easier it is important to acquaint yourself with the EEG structure. Just look around all the variables (especially in EEG.event for this case particularly) to see how they are all related to each other and what kind of information is in them (string, double, etc).</div><div><br></div><div>What you want this script to do is find all the events labeled '13', find their latency and then use those latencies to calculate the latencies for your added events, right? In the example script, the event label is a string, so it uses strcmp which compares the given string ('A') to the strings in EEG.event.type. If your event is not a string, then you shouldn't use strcmp, but just work with the number 13.</div><div><br></div><div>I hope this at least in part helps you towards a solution.</div><div><br></div><div>cheers,</div><div>Raquel</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">--<div>Dragón de la Patagonia</div><div>Ramon Barros Luco 688<br>Puerto Natales - Patagonia - Chile <br>Oficina: +56-9-94022038</div><div>Skype: raquel.london</div><div><br></div></div></div></div>
