<div>Nabaraj,</div>
<div> </div>
<div>you may be interested in looking into wireless EEG systems from QUASAR (<a href="http://www.quasarusa.com/">http://www.quasarusa.com/</a>). We have used their system for acquiring EEG from Soldiers in field conditions. QUASAR should be able to provide you with documentation regarding system performance. It's very close to clinical quality. In addition they are working on enhancements to enable high quality EEG capture in non-ideal environments (like Soldiers riding around in the back of vehicles controling robotics). The EEG output can be read into EEGLab after some minor manipulation. </div>

Dear Joaquin,<br>that has lots of sense, but if you 130 IC in one cluster, is that still OK or an indicator that larger number of clusters is needed? Would you recommend increasing number of clusters all until each cluster contains at least 1 IC from each subject? My experience is that this results in generating similar clusters.<br>
Also I have noticed that cluster dipole gives deeper location of sources then I would expect. Is that right?<br>Regards,<br>Alex<br>.________________________________________<br>From: Joaquin Rapela [<a href="mailto:rapela@ucsd.edu">rapela@ucsd.edu</a>]<br>

<div>as in psychometrics and factor analyses,</div>
<div>it is a good idea to evaluate different clustering solutions, and checking the stability of one's main pattern of IC findings,</div>
<div>another option is to simply use corrmap to find all the similar brain ICs</div>
<div> (for example all the ICs reflecting a traditional P1 component topography and timecourse).</div>
<div>Clusters that you develop should generally match up these similar scalp maps, even if you use </div>
<div>other information such as dipoles, ersp, etc.. as clustering information.</div>
<div>Another option is to attempt use of the measure projection plugin as an alternative to clustering, but there are still</div>
<div>user decisions to be made there as well.</div>
<div>What we could use, generally speaking, is a measure of how much variance in the data is accounted for by each cluster solution,</div>
<div>compared to other solutions.</div>
<div>all the best! please let us know your choice of solution!</div><br><br><br>

"Frames" in EEGLAB are the same as samples (so if you sampled at 1000 Hz your data will have 1000 frames each second).<br>
<br>As for epochs: you are right that the EEG is collected continuously, but part of the procedure for analyzing event-related potentials from EEG is to later "chop" the signal into segments time-locked to an event such as a stimulus (see Luck, 2005, </font></span><i><span style="FONT-SIZE:x-small"><font face="arial, helvetica, sans-serif">An Introduction to the Event-Related Potential Technique</font></span></i><span style="FONT-SIZE:x-small"><font face="arial, helvetica, sans-serif">). EEGLAB treats the continuous data as consisting of one long epoch, whereas after chopping up the data it consists of multiple small epochs. So that's why you see EEGLAB reporting that there is one epoch even when you are loading continuous data.<br>
