<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hello all,<br><br>I am interested in importing epoched Neuroscan data into EEGLAB to perform ICA artifact correction (the continuous files are much too large to import without chopping them into several smaller files each). I tried epoching the files in Neuroscan's software while including all conditions (such that each epoched file contained epochs with different trigger values, e.g. '1','2','3','4'), but after importing into EEGLAB every epoch seems to have the same trigger value, 'TLE'. I had intended to extract the epochs for each condition into separate datasets to perform averaging and further analysis by condition, but of course if the epochs no longer have triggers that identify their condition that is difficult. <br>
<br>Does anyone know how to preserve the event/trigger information when importing Neuroscan .eeg data? Any suggestions would be much appreciated!<br><br>Best,<br>Stephen Politzer-Ahles<br clear="all"><font color="#888888"><br>
