Hi Simone,<br class="">
<div>
<div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">
<div class=""><br class="">
</div>
<div class="">What is the question behind the question?</div>
<div class=""><br class="">
</div>
<div class="">The reason I ask this is because overcomplete layout files (i.e. files containing more channels than you need) don’t prevent you from visualizing your own data.</div>
<div class=""><br class="">
</div>
<div class="">If you anyhow want to manually remove channels (and the corresponding information in pos/height etc) your code is not foolproof, most likely because setdiff may inadvertently alphabetize the labels, causing the mismatch you report.</div>
<div class=""><br class="">
</div>
<div class="">you could do:</div>
<div class=""><br class="">
</div>
<div class="">remove = {…};</div>
<div class="">sel = ismember(lay.label, remove);</div>
<div class=""><br class="">
</div>
<div class="">lay.pos = lay.pos(~sel,:);</div>
<div class="">lay.height = lay.height(~sel);</div>
<div class=""><br class="">
</div>
<div class="">etc.</div>
<div class=""><br class="">
</div>
<div class="">Best,</div>

<div class="">I was wondering whether someone could give us some advice on how to adapt an existing layout file.</div>
<div class=""><br class="">
</div>
<div class="">We would like to adapt easycapM1.mat, as our own layout is highly similar. Specifically, we would like to remove F1, F2, FT7, FT8, TP7, TP8, CP1 and CP2. In addition, we would like to add the mastoids (for ICA plotting purposes).</div>
