Dear Jonathon,
<div class=""><br class="">
</div>
<div class="">What you want to achieve should be possible, but fails in your case probably due to the fact that the ‘chantype’ key only works if the values provided match the entries in (your) electrode_map.chantype field. So, providing channel labels, as I
interpret from the description in the e-mail, is not going to work. </div>
<div class=""><br class="">
</div>
<div class="">You probably need to do something like this (no success guaranteed, but you can use the below snippet of code to get started):</div>
<div class=""><br class="">
</div>
<div class="">stim_idx = match_str(electrode_map.label, {stimA,stimB});</div>
<div class="">rec_idx = match_str(electrode_map.label, {RecA,RecB});</div>
<div class="">if ~isfield(electrode_map, ‘chantype’)</div>
<div class=""> for k = 1:numel(electrode_map.label)</div>
<div class=""> electrode_map.chantype{k,1} = ‘unknown’;</div>
<div class=""> end</div>
<div class="">end</div>
<div class="">electrode_map.chantype(stim_idx) = {’stim’};</div>
<div class="">electrode_map.chantype(rec_idx) = {‘rec’};</div>
<div class=""><br class="">
</div>
<div class="">ft_plot_sens…</div>
<div class="">ft_plot_sens(…, ‘chantype’, ’stim’);</div>
<div class="">ft_plot_sens(…, ‘chantype’, ‘rec’);</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
