The idea is that the long "vertical" streaks, or "smears" in your graph are the result of multiple distinct frequency bands being somehow lumped or averaged together within each time point, leading to the impression that at a given moment in time, many different frequency bands are all highly correlated (i.e. all having high power at the same time).

<br>
I'm using the STUDY function to compute ERSPs for a dataset with 18 subjects and 3 conditions per subject. The ERSPs take a number of hours to compute, so I'd like to set up a parfor loop to create the "xxx.datersp" files in parallel using our distributed processing network.<br>
<br>
This post indicates that it should be possible to set up the parfor loop: <a href="http://sccn.ucsd.edu/pipermail/eeglablist/2014/008914.html" target="_blank">http://sccn.ucsd.edu/pipermail/eeglablist/2014/008914.html</a> . However I'm not sure which of the functions involved in the ERSP computation is the one I should attempt to parallelize (std_precomp.m, std_ersp.m or newtimef.m?), and which of the for loops I should be editing.<br>
<br>
Does anyone have any insight into how to set this up?<br>
<br>
Thanks!<br>
<br>
Tom<br>
<br>
p.s. this is the function I'm currently using to create the ERSPs:<br>
<br>
[STUDY ALLEEG] = std_precomp(STUDY, ALLEEG, {},'interp','on','recompute','on','ersp','on','erspparams',...<br>
{'cycles' cycleParam 'nfreqs' 27 'timesout' [0:100:3000] 'freqs' [4 30] },'itc','off');<br>

<div>
<p>Dear colleagues,</p>
<p> </p>
<p>The Laboratory of Neuropsychopsysiology of the University of Porto (<a href="http://www.fpce.up.pt/labpsi/" target="_blank">http://www.fpce.up.pt/labpsi/</a>) is pleased to announce the 4th edition of the International Cognitive and Affective Neurophysiology Summer School:
Acquisition, processing, and analysis of EEG signal. </p>
<p> </p>
<p>This summer school is focused on the application of Electroencephalography (EEG) and Event Related Potential (ERP) techniques to the study of cognitive and affective processes. The course will be fully taught in English and is aimed at an introductory level,
so no previous experience with EEG or ERP is required.</p>
<p> </p>
<p>This event will take place from 7-12 of September 2015 in the lovely city of Porto.</p>
<p> </p>
<p>In last year’s edition the course was fully booked and, as such, we recommend early registration (course places are attributed by order of registration).
</p>
<p> </p>
<p>For additional details and instructions on how to register, please consult our website (<a href="http://www.fpce.up.pt/labpsi/summerschool/" target="_blank">http://www.fpce.up.pt/labpsi/summerschool/</a>).</p>
<p> </p>
<p> </p>
<p>Please feel free to pass this information along to students or researchers that may be potentially interested.<br>

</div>
<div>I am trying to reorganise the order of trials in my EEG .set files. </div>
<div>I was hoping to use the following function:</div>
<div>EEG = pop_selectevent( EEG, 'epoch',[] ,'deleteevents','off','deleteepochs','on','invertepochs','off');</div>

<div>Based on behavioural data, we create two or more sub-sets from one EEG recording. However, within these sub-sets, the order in which stimuli were presented is not the same. Is there a way for me to reorganise the order of trials and save that order in
a new .set file? E.g., </div>
<div><br>
</div>
<div>List 1</div>
<div>EEG = pop_selectevent( EEG, 'epoch',[1:9] ,'deleteevents','off','deleteepochs','on','invertepochs','off');</div>

<div>
<font face="Calibri" size="2"><span style="font-size:11pt">
<div>Dear Eeglab members, <br>
<br>
Before manually selecting artifacts in my data, I would like to pre-select artifacts automatically. I have seen that Eeglab provides an automatic epoch rejection toolbox, but specific epoch selection that I would like to make, does not seem to be provided.
<br>
e.g.; I would like to remove epochs where the difference between the maximum and minimum in an interval of a selectable length, and the difference between the maximum and minimum in the epoch itself, exceeds a specific value. Also, I’d like to remove epochs
wherin the absolute difference between two neighboring sampling points exceeds a certain value.
<br>
<br>
Does anyone have an idea if this is possible in Eeglab automatically? Or perhaps it is possible that I script this separately?
<br>
<br>
Many thanks in advance<br>
<br>
Dana </div>
