<div>Hi Pan,<br>
<br>
The size of the first (or smallest) dimension of<font face="Courier New"> EEG.icaweights</font> will always indicate the number of components in a given data set. So, in your script you can use<font face="Courier New"> [1:min(size(EEG.icaweights))]</font> for
a generic "all components" elec_comp input to pop_eegthresh.<br>

<div><font face="Helvetica">Hi colleagues,</font></div>
<div><font face="Helvetica"></font> </div>
<div><font face="Helvetica">I'm using the <em>pop_eegthresh </em>function for epoch rejection based on component activities:</font></div>
<div><font face="Helvetica"></font> </div>
<div><font face="Helvetica"><em>[EEG Indexes] = pop_eegthresh( INEEG, typerej, elec_comp, lowthresh, upthresh, starttime, endtime, superpose, reject)</em></font><br clear="all">
</div>
<div>in which <em>elec_comp </em><font face="Helvetica"><em>[e.g., 1:32]</em> </font>
referes to the number of channel<font face="Helvetica">s or components selected for epoch rejection.</font></div>
<div><font face="Helvetica"></font> </div>
<div><font face="Helvetica">I want to run the script on a batch of .set files which have different numbers of components. Since it would be time-consuming to adjust the values of
<em>elec_comp</em> file by file, I'm wondering wether </font><font face="Helvetica">there is a default setting of
<em>elec_comp,</em> </font><font face="Helvetica">which will automatically take ALL components into consideration for each file. I tried to leave the bracket blank but it turmed out to be a default of "0" (0 component was selected for rejection).</font></div>
<div><font face="Helvetica"></font> </div>
<div><font face="Helvetica">Thanks for your input! </font><font face="Helvetica">Pan</font></div>
