</div>
<div> Thank you for the reply. </div>
<div> Can you send me some good figures of frequency power spectrum of the IC.Also can you share the independent components of a good EEG data. </div>

<div>Sorry to tell you this but the 21 ICs are all noise.</div>
<div><br>
</div>
<div>I strongly recommend you perform preprocess again. Read this page and check the steps. You may want to consider using PREP pipeline by Nima Bigdely-Shamlo (described in the wiki).</div>

</div>
<div>Good ICs are determined by</div>
<div>1. Dipolarity of the IC scalp maps (see Delorme et al. 2012 PLoS One)</div>
<div>2. Frequency power spectrum of the ICs</div>
<div>3. ERP or ERSP (if available)</div>
<div>Note this kind of evaluation (or interpretaion) is dependent on the experimental paradigms.</div>
<div><br>
</div>
<div>Also, remember 'Garbage in, Garbege out'; if the experimental design is screwed up, you don't get EEG even if you use the fanciest preprocessing methods.</div>
