Hi Gema,
<div class=""><br class="">
</div>
<div class="">It seems that ft_channelrepair is in the air today. Just for the record, this will be the last e-mail I will answer on the discussion list today, specifically one about ft_channelrepair…</div>
<div class=""><br class="">
</div>
<div class="">I think that using the non-preferred ‘weighted’ method in ft_channelrepair does not require an elec description. However, you should specifiy cfg.badchannel as a cell-array (at least that’s what I gather from the function’s help, and what I think
I understand from the low level errors you report).</div>
<div class="">In other words, rather than cfg.badchannel = ‘C1’, you should call cfg.badchannel = {‘C1’};</div>
<div class=""><br class="">
</div>
<div class="">Then I would think that the following could work...</div>
