Hi Habib,<br><br>Once you open the two datasets, you can use the Edit >> Append datasets command from the GUI (or the pop_mergeset() command from the MATLAB command line) to merge the dataset. <br><br>As for how to count events, there are a few ways to do it. If you just want to know the overall number of events in the file, this is shown in the "Events" field of the EEGLAB interface when you open a dataset. If you want to know the number of a particular sort of event, you can get that information from the EEG.event field (what I do is write a 'for' loop in MATLAB that goes through each item in EEG.event and keeps track of how many events of each type it finds), or you can epoch the dataset based on that particular event type and then see how many events are left in the new dataset. (There may be simpler ways to count events; I don't know of any other ways, but someone else on the list might.)<br>
