I got this to work after realizing that the electrode positioning was in ASA format. After this, using ft_electroderealign worked perfectly. Thank you very for your helpful answer.</div>

<div>Hi Guillermo,
<div class=""><br class="">
</div>
<div class="">If you say: ‘generic’, you probably meant ’subject-specific’? Either way, if there’s a way that you can get the 3D electrode positions into a representation that FieldTrip knows as an ‘elec’-structure (did you check whether ft_read_sens works
for you?), then you can use the function ft_electroderealign. I think there should be sufficient documentation in the function’s help, and on the website to get you started.</div>
<div class=""><br class="">
</div>
<div class="">Good luck</div>

Currently, I am working with EEG recordings from 256-channel ANT Neuro caps. The data includes the EEG time series, and geometric data in the form of a generic mesh (consisting of nodes and triangles) with nodes given by electrode positions, which were digitized
using ANT Neuro xensor. To be more precise, I have geometric data of the form </div>
