<div dir="ltr">Dear Luigi,<div><br></div><div>I know you have already addressed the problem, but for record I can also recommend to use James Desjardin's vised() plugin. You can install this plugin from the EEGLAB plugin manager, with which you can create the very first event during browing the continuous data (use keyboard shortcut ctrl + click or something to add event interactively.)</div><div><br></div><div>From UA49 to Newark,</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jan 12, 2017 at 9:54 PM, Makoto Miyakoshi <span dir="ltr"><<a href="mailto:mmiyakoshi@ucsd.edu" target="_blank">mmiyakoshi@ucsd.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Dear Luigi,<div><br></div><div>Yeah it's annoying that if you don't have any event then you can't create event information.

Probably 2) is more proper and supported way to go. You can do this from EEGLAB main GUI, 'File' - 'Import event info'.</div><div><br></div><div>Dear Stephen,</div><span class=""><div><br></div><div><span style="font-size:12.8px">> another was to use a built-in EEGLAB function to split up the signal into equal-length segments.</span><br style="font-size:12.8px"></div><div><span style="font-size:12.8px"><br></span></div></span><div><span style="font-size:12.8px">Hmm that could be eeg_regepoh(), but it's not partucularly useful for this purpose. In addition, when I recently used it, it did not work well when I specify 10 s epoch for example... or maybe I did not understand how to use it even though I read the help file 5 times i.e. probably some kind of bug is there and segmenting the data into 1-s is the only confirmed good behavior. I don't know what was wrong.</span></div><div><br></div><div>From Lufthansa455 to Frankfurt,</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Wed, Dec 28, 2016 at 3:07 AM, Luigi Pavone <span dir="ltr"><<a href="mailto:gi19gi82@gmail.com" target="_blank">gi19gi82@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><div style="font-size:12.8px">Hello everybody,</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I'm new in eeglab, I would like to ask you some questions.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I have a continuos 17 channels EEG signal.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I would like to extract epochs from that signal.
