<div dir="ltr">Yeah it may be 'varargin' for all the inputs... in that case I would use a debug mode to stop the execution at some line and use GUI with desired param. When the process is stopped check varargin to learn what's inside. Or it may be kindly described somewhere in SIFT manual or his function.

<div dir="ltr">Hmm... is that because you are using 'NormalizeData'? To test this, why don't you make comparison with and without it? The low end does look attenuated, which makes sense.
<div><br>
</div>
<div>By the way uncheck 'use single precision...' option when you use SIFT.<br>

<p>Is there a necessary step after that? If you just wanted to detrend your data.<br>

<div>Yes, that sounds right. I don't think SIFT changes EEG.data.</div>

<p>Hello eeglabers,<br>
</p>
<p><br>
</p>
<p>I have a question about detrending in SIFT.<br>
</p>
<p><br>
</p>
<p>I run the following code:<br>
</p>
<p><br>
</p>
<div>EEG = pop_pre_prepData( EEG, 'nogui', ...</div>
<div> 'VerbosityLevel', 2, ...</div>
<div> 'SignalType', { 'Channels'}, ...</div>
<div> 'Detrend', ...</div>
<div> { 'verb', 2 ...</div>
<div> 'method', {'linear'}, ...</div>
<div> 'piecewise', ...</div>
<div> {'seglength', 0.33, ...</div>
<div> 'stepsize', 0.0825}, ...</div>
<div> 'plot', strcmp( plot, 'on')}, ...</div>
<div> 'NormalizeData', ...</div>
<div> {'verb', 2 ...</div>
<div> 'method', {'time' 'ensemble'}}, ...</div>
<div> 'resetConfigs',true);<br>
</div>
<div><br>
</div>
<div>It works fine, but I do an is equal on the data before and after and they are identical.<br>
</div>
<div><br>
</div>
<div>Im thinking this cant be correct because it should be removing a significant proportion of my data.<br>
</div>
<div>I went through the code and it appears as though it is storing the data in <a href="http://EEG.CAT" target="_blank">
EEG.CAT</a>. Have I missed<br>
</div>
<div>something or am I doing it correctly?<br>
</div>
<div><br>
</div>
<div>Kind regards,<br>
</div>
