<div class="gmail_extra">Hi Tarik,</div><div class="gmail_extra"><br></div><div class="gmail_extra">thank you for your answer.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Regarding overlapping of the segments, I did not presented it well when I wrote the different names of the markers since markers I am talking about present the same subject's "activity" (so all of them are for example M1). They are of a same kind and since they are not homogeneously distributed, I have some parts where I will surely have some epoch overlapping (and if I put smaller epoch boundaries, I wouldn't get enough information).</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">Regarding markers exporting, I solved the problem without any exporting and importing. I simply put the markers (Edit --> Visually edit markers and...) on the sensor signal (which is loaded together with the rest of eeg signals in one EEGLAB dataset) and afterward I just erased sensor signal, but the markers remained, which is exactly what I needed.</div>

<br></div><div>1. Is it possible somehow to export marker events (their latency) I put manually (Edit --> Visually edit events and identify bad channels) into the data and import them to other dataset?</div>
<div>I have a sensor measuring the activity I am interested in which of course, gives as an output signal with much higher amplitude than eeg signal. Because of that, I am plotting it separated from eeg signal, in order to see its shape and to be able to put some additional markers in accordance with the signal of the sensor. Since it is plotted (and imported into) EEGLAB separated from eeg signal, I am not sure how to import new marker events allocated in sensor signal to another dataset (eeg) which is to be analysed.</div>
<div><br></div><div>2. When determining the limits of the epochs to extract (around the event markers) do I have to take care that two epochs do not have boundaries that overlap? If yes, please give some short explanation, if not - then great =)</div>
<div>Example: Marker1 happened in 1st second and Marker2 in 3rd second. If I put -1 and 2.5 as an epoch boundaries there will be some overlapping.</div><div><br></div><div>Thank you in advance (answers from my previous questions were of a great great help to me).</div>
