<div dir="ltr">Dear Laith,<div><br></div><div>thanks for your question. You could refer to a factory schematic layout such as the one in figure 4 of this publication:</div><div><a href="http://journal.frontiersin.org/article/10.3389/fnhum.2011.00159/abstract">http://journal.frontiersin.org/article/10.3389/fnhum.2011.00159/abstract</a><br></div><div><br></div><div>and subsequently use the function ft_prepare_layout to manually track the points of the custom design on your own (if you dont want to wait for somebody from the FT to do the same for you).</div><div><br></div><div><pre class="" style="padding:0.5em;margin-top:0px;margin-bottom:1em;font-size:12px;border:1px dashed rgb(204,204,204);color:rgb(0,0,0);overflow:hidden;font-family:Consolas,'Andale Mono',Menlo,Monaco,monospace;white-space:pre-wrap;width:640px;text-align:justify;background-color:rgb(247,249,250)">cfg = [];

<p>Dear community,</p>
<p>My name is Laith Hamid and I am working in the University Medical Complex of Schleswig-Holstein in Kiel on source analysis of epileptic spikes and seizures. Currently I am analysing an EEG data set that was recorded using a 256-channel EGI system and I wanted to ask whether you have a standard BEM or FEM head model that extends enough downwards to accomodate all 256 electrodes. The current standard BEM model in the template folder of Fieldtrip isn't appropriate for source analysis of 256-channel EGI data.</p>
<p>Thank you very much in advance for your help!</p>
<p>Best,</p>
<p>Laith</p>
