Date: Mon, 13 Oct 2008 17:45:00 +0200<br>Subject: [Eeglablist] compare different electrode setups<br>Dear list,<br>
<br>
I want to compare and eventually to grand average the data recorded in different subjects in the identical conditions, software and almost the same hardware (from Brain Products), except that the electrodes schemes are different. Can I extrapolate them to a virtual electrodes scheme (I believe this is how it is done in BESA)? Or maybe other solutions?<br>
Thanks in advance.<br>
<br>
Yours,<br>
Nikolai Novitski <br>

<p><font size="2" face="Arial">Hi EEGLAB list.</font>
</p>
<p><font size="2" face="Arial">I'm currently trying to track down the source of a problem i have plotting condition and group ERP's from the STUDY channel measures menu.</font></p>
<p><font size="2" face="Arial">I have all the 'group' and 'condition' data loaded into the EEG.group and EEG.condition. The correct group and condition numbers pop up in the study info window when all the subjects are loaded into the study.. In EEG.group and EEG.condition the values are strings (but numerals). I have groups '1' and '2', and conditions '111' and '122'.</font></p>
<p><font size="2" face="Arial">The study looks like this</font>

</p>
<p><font size="2" face="Arial">Now, when plotting the channel measures, I select "plot conditions on the same panel", and get two plots as expected. The first (group '1') has two lines, as expected. One is labelled '111' and the other '122'. All OK. However underneath there is an empty plot, labelled '2', but with no lines.</font></p>
<p><font size="2" face="Arial">I thought this might be somehow a fault in my data or the way the conditions and groups are entered (maybe they should be numbers, not strings?) so I tried loading the example data (5subjects.zip), and added a group variable. Same problem however.</font></p>
<br>
<p><font size="2" face="Arial">Anyone had any luck with this before?</font>

<br>
I am trying to find some literature on Frequency Analysis using EEGLAB, specifically Event Related Oscillations using ERPs. I am interested in finding out more on the methodology used, how to prepare the EEG data and what analytic choices have been used, e.g bandpass filter etc..<br>
<br>
Any information would be great, thank you for your help,<br>
