<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">During artifact rejection (in summary mode), I had to remove the F7 channel for some of my subjects. I'm now trying to replace these missing channels but I'm having some difficulties.
<o:p></o:p></p>
<p class="MsoNormal">Since I only have 28 channels (excl. eye and reference) and F7 is all the way on the front left, I thought using the average method would be the best. After some trial and errors, I now have this:<o:p></o:p></p>
<p class="MsoNormal">cfg = []; <o:p></o:p></p>
<p class="MsoNormal">cfg.method = 'template'; <o:p></o:p></p>
<p class="MsoNormal">cfg.template = 'custom_easycap32.mat';<o:p></o:p></p>
<p class="MsoNormal">cfg.channel = {'F7'};<o:p></o:p></p>
<p class="MsoNormal">neighbours = ft_prepare_neighbours(cfg, data_nat_clean)<o:p></o:p></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">cfg = []; <o:p></o:p></p>
<p class="MsoNormal">cfg.method = 'average'; <o:p></o:p></p>
<p class="MsoNormal">cfg.layout = 'custom_easycap32.mat'; <o:p></o:p></p>
<p class="MsoNormal">cfg.missingchannel = ft_channelselection('F7', data_nat_clean.label);<o:p></o:p></p>
<p class="MsoNormal">cfg.neighbours = neighbours; <o:p></o:p></p>
<p class="MsoNormal">data_nat_chan = ft_channelrepair(cfg, data_nat_clean)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If I run this code, I get the following which I think is due to an error in the first part:<o:p></o:p></p>
<p class="MsoNormal">Trying to load sensor neighbours from a template<o:p></o:p></p>
<p class="MsoNormal">Successfully loaded neighbour structure from custom_easycap32.mat<o:p></o:p></p>
<p class="MsoNormal">Improper index matrix reference.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Error in ft_prepare_neighbours (line 219)<o:p></o:p></p>
<p class="MsoNormal">neighb_chans = {neighbours(:).label};<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What does this error mean and how can I fix this? I have also tried some things without the first part, but then either it said that everything worked at the resulting data still had 27 channels (so without the F7) or I got an error saying
there is a reference to non-existing field 'neighbours' . <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I hope someone can help me out!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
<p class="MsoNormal">Mary-Jo <o:p></o:p></p>
