Currently I'm trying to interpolate EEG data from an EGI system using ft_channelrepair. I run into the same error as is described in this thread: <a href="https://mailman.science.ru.nl/pipermail/fieldtrip/2014-March/033537.html">https://mailman.science.ru.nl/pipermail/fieldtrip/2014-March/033537.html</a> but
can't seem to find the solution.</div>

It seems that the ft_prepare_neighbours works well, as the neighbours are described and make sense. The error occurs if I automatically detect the bad channel, if I manually define it, if I use any type of method. For example in the following script where row
and column represent a specific channel and trial (which are correctly identified, and the cfg.badchannel shows the actual channel name)</div>
