<p class="MsoNormal"><span style="color:#1F497D">I am trying to calculate the mean value of an ERP over a specific timeframe (300-500 ms post stimulus (N400)), separately for each channel. But I can’t seem to find how to do that with EEGLab. I already used
the averaging functions (e.g., <a href="http://cognitrn.psych.indiana.edu/busey/temp/eeglabtutorial4.301/maintut/data_averaging.html" target="_blank">
<span style="color:#1F497D">http://cognitrn.psych.indiana.edu/busey/temp/eeglabtutorial4.301/maintut/data_averaging.html</span></a>) for other purposes, but what I would like to have now is one mean value (potential) per subject per condition. I need to prepare
the data for a colleague who is going to process the data further in SPSS. </span>

<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">I have epoched the datasets for all of my subjects and conditions (Subject1condA, subject2condB, etc.). What to do next?</span></p>
