<span id="result_box" class="" lang="en"><span class="hps">Hello
guys</span><span>,<br>
<br>
I recently</span> <span class="hps">started using</span> <span
class="hps">eeglab</span> <span class="hps">with which</span> <span
class="hps">I would like to</span> <span class="hps">carry out</span>
<span class="hps">a dipole fitting</span><span class="hps"> on
ERPs data (N100).</span><br>
<span class="hps">I usually use</span> <span class="hps">BrainVision</span>
<span class="hps">Analyzer</span> <span class="hps">to work with</span>
<span class="hps">ERPs</span><span>, but</span> <span class="hps">this</span>
<span class="hps">software cannot do</span> <span class="hps">the
</span><span class="hps">dipole localization.<br>
<br>
</span><span class="hps">I</span> <span class="hps">cleansed</span>
<span class="hps">the signals with</span> <span class="hps">ICA</span>
<span class="hps">(on</span> <span class="hps">BrainVision</span>
<span class="hps">analyzer)</span><span>, I ran</span> <span
class="hps">an average</span> <span class="hps">of the
different epoques </span><span class="hps">and</span> <span
class="hps">I imported</span> <span class="hps">the data</span>
<span class="hps">(65</span> <span class="hps">sensors</span><span>,
70</span> <span class="hps">time points</span><span>)</span> <span
class="hps">in</span> <span class="hps">eeglab</span><span>.</span>
<span class="hps">Then I followed</span> <span class="hps">the
tutorial about </span><span class="hps">dipfit
(<a class="moz-txt-link-freetext"
href="http://sccn.ucsd.edu/wiki/A08:_DIPFIT#Using_DIPFIT_to_fit_EEG_or_ERP_scalp_maps">http://sccn.ucsd.edu/wiki/A08:_DIPFIT#Using_DIPFIT_to_fit_EEG_or_ERP_scalp_maps</a>)</span>
<span class="hps">but I have not</span> <span class="hps">got
encouraging results</span><span>.</span><br>
<span class="hps">For this reason</span> <span class="hps">I ask
you</span> <span class="hps">some indication of the</span> <span
class="hps">method to be followed</span><span>, if it is</span>
<span class="hps">necessary or not</span> <span class="hps">perform</span>
<span class="hps">dipfit</span> <span class="hps">of</span> <span
class="hps atn">ICA (</span><span>but</span> <span class="hps">which
components</span><span> and how should be selected?) or</span> <span
class="hps">can I use</span> <span class="hps">dipfit_erpeeg</span><span>.</span><br>
<span class="hps">I really hope</span> <span class="hps">in</span>
<span class="hps">a</span> <span class="hps">help.</span><br>
<span class="hps">Thanks in advance</span><span>.</span><br>
