<br>
I just came across a bug in the eegplot function that may account for the shifted rejection boundaries you reported finding while scrolling through your continuous data.<br>
<br>
If the paging buttons { [ << ] or [ >> ]} are quickly clicked twice it can happen that the signals will advance two windows, while the events will only advance 1 window (e.g. if you are displaying 50 seconds at a time and the current window starts at 100 seconds...
then you double click [ >> ] quickly, the figure will display the signals from 200 to 250 seconds but the events that will be superimposed are the events for the time period of 150 to 200 seconds).<br>
<br>
This is a relatively harmless bug as it is only display... any further interaction with the GUI (including selecting time for rejection) refreshes the figure and the offset is corrected.<br>
<br>
Let me know if this could account for all of the symptoms that you found while scrolling your continuous data.<br>
<br>
I have reported this in EEGLab bugzilla (#1393) and will look into solving the issue over the next few days.<br>

<div>Dear Makoto,<br>
<br>
I recorded my data using Biosemi Active two system with 64 electrodes at <br>
256Hz. Data were band pass filtered at 0.1-20 Hz and re-referenced <br>
offline first to nose reference to remove bad channels. Removed channels <br>
were interpolated and the data were re-referenced to average reference. <br>
I then checked the continuous data for non-typical artifacts, removed <br>
them, and saved the data with a new name. The shifted rejection <br>
boundaries problem appeared in this new data set.<br>
<br>
Kindly let me know if I need to provide any other information.<br>
<br>
Thank you.<br>
<br>
Regards,<br>
Maria<br>
