<p>Hi all,</p>
<p> </p>
<p>Sorry for the basic question, but I am struggling to understand exactly what the ersp values produced by timef represent. I thought that I understood the analysis at a reasonable level, but now that I have run the analysis I'm not sure which values I should
be extracting in order to average across participants.</p>
<p> </p>
<p>I have data from 128 channels, (re)sampled at 500hz. One specific question I have is what the x and y coordinates of the 'ersp' variable represent? I have read the help file and various other documents, but can't work out what 'nfreqs' and 'timesout' actually
mean- why is ersp a 256x200 matrix?</p>
<p> </p>
<p>Any help greatly appreciated,</p>
<p>Katherine </p>

<div>Dear EEGlab Community,<br>
<br>
</div>
I wonder if anyone can help me with the following issue:<br>
</div>
>From my Study design, I would like to extract (for each participant and condition) the average power in a specific frequency band and a specific time window. I would like to export these values into SPSS for statistical analysis.<br>
</div>
I should also note that I am working with IC Clusters, so the above ERSP measures should be cluster specific.<br>
</div>
Does anyone know a script which would help me achieve this?<br>
<br>
</div>
Yours gratefully,<br>
</div>
Nikola<br>
