Hi Peter,
<div class=""><br class="">
</div>
<div class="">ft_read_data is a so-called ‘intermediate’ level fieldtrip function and not typically called directly by the casual user. </div>
<div class=""><br class="">
</div>
<div class="">I think your use case calls for the following strategy:</div>
<div class=""><br class="">
</div>
<div class="">channellist = {‘channel1’;’channel2’;…’channelN’};</div>
<div class="">for k = 1:numel(channellist)</div>
<div class=""> cfg.channel = channellist{k}; % or something equivalent, at least instructing the reading function to grab a channel specific file</div>
<div class=""> data{k} = ft_preprocessing(cfg);</div>
<div class="">end</div>
<div class=""><br class="">
</div>
<div class="">alldata = ft_appenddata([], data{:});</div>
<div class=""><br class="">
</div>
<div class="">Once you have the alldata object, you can apply re-referencing. Perhaps indeed this is best done by creating a ‘montage’, and apply it to the data.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
<div class=""><br class="">
