<p style="margin-top:0px;margin-bottom:0px">Carol, I think you do have to edit the EasyCap layout - you download it, keep it as a .txt file, and just edit the text file. Then when you call cfg.elec just make sure you are directing fieldtrip to this edited file.
This is what I did with 64Ch Brain Vision data when I needed to call the electrode positions - you will need to do this again during cluster-based permutation testing so worth having the file ready now</p>

</div>
<div>I am trying to use the function "ft_channelrepair", but I can't figure out how to configure the EEG electrodes position.</div>

<div>The EEG cap I used is the "Acticap 64ch standard".</div>

<div>in which "filename" = template 3D electrode set available on <<a href="https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ffieldtrip%2Ffieldtrip%2Ftree%2Fmaster%2Ftemplate%2Felectrode&data=01%7C01%7Celizabeth.1.shephard%40kcl.ac.uk%7C884e368c63dd4f5a176b08d70fb9199c%7C8370cf1416f34c16b83c724071654356%7C0&sdata=8twyT5Q71yDZhhPR0AzjWvTeK%2BcEFO0Ev%2FpRJQv6YkM%3D&reserved=0" id="gmail-m_-4193349214764970044LPlnk917308" class="gmail-m_-4193349214764970044OWAAutoLink" target="_blank">https://github.com/fieldtrip/fieldtrip/tree/master/template/electrode</a>>.
There is no template available for the "Acticap 64ch standard" on the mentioned website, though.</div>
<div><br>
</div>
<div>Then, I thought it would be valid editing the "easycap-M1.txt" template (which is available), and transforming it into the "Acticap 64ch standard", which apparently would involve deleting 8 channels and renaming two, as described on <<a href="https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.fieldtriptoolbox.org%2Ftemplate%2Flayout%2F%23acticap-64ch-standard2mat&data=01%7C01%7Celizabeth.1.shephard%40kcl.ac.uk%7C884e368c63dd4f5a176b08d70fb9199c%7C8370cf1416f34c16b83c724071654356%7C0&sdata=jN2AvJIsXuhjM%2Fi4vSPu%2BmHdVo%2FTxcuUSpR3Gq7YF18%3D&reserved=0" id="gmail-m_-4193349214764970044LPlnk123377" class="gmail-m_-4193349214764970044OWAAutoLink" target="_blank">http://www.fieldtriptoolbox.org/template/layout/#acticap-64ch-standard2mat</a>>.</div>
<div><br>
</div>
<div>However, I don't know how can I do this and I'm not sure if this would be the proper way to solve this.</div>
<div><br>
</div>
<div>Can someone please tell me:</div>
<div>1. If this solution would be valid or if there is any other way to solve this?</div>
<div>2. In case it is valid, do I have do I have to download the "easycap-M1.txt" file, convert it into a ".m" file and then edit it? </div>
