<div class="">Hi Masoud,</div>
<div class=""><br class="">
</div>
I don’t know why the whole story about neighbours would be relevant to the problem you are facing. Clearly, the error you report:
<div class=""><br class="">
</div>
<div class="">
<blockquote type="cite" class="">

<div class="gmail_quote">

</div>
</div>
</div>
</div>
</div>
</div>
</blockquote>
<div class=""><br class="">
</div>
is caused by an issue with the call to the matlab builtin setdiff function. In other words, there is something unexpected going on with the cfg.missingchannel/data.label combo. Have you tried to debug this by setting a breakpoint on line 204 in ft_channelrepair
and investigate cfg.missingchannel, and data.label at that point during code execution?</div>

Hello again. Sorry for bothering you again, I know you are probably very busy but I Would appreciate it if you take your time and answer my question, I have been stuck in it for a while and just a little insight from you might help me overcome this problem.

Subject: a question in neighbours and channelrepair<br class="">

<div dir="ltr" class="">Hello, I am currently using the fieldtrip matlab toolbox for preprocessing an EEG dataset. I want to interpolate the CZ channel with its neighbours, all three methods of ft_prepare_neighbours function have been used.
<div class="">1- I used the distance method in ft_prepare_neighbours function but the output is:<br class="">
<div class="">Warning: no neighbours found for CZ<span class="Apple-converted-space"> </span><br class="">
In ft_prepare_neighbours at line 384<br class="">
<br class="">
Warning: No neighbouring channels were specified or found<span class="Apple-converted-space"> </span><br class="">
In ft_prepare_neighbours at line 390 (I changed the value of cfg.neighbourdist multiple times but no changes has occurred)<br class="">
</div>
</div>
<div class=""><br class="">
</div>
<div class="">2- The output of the triangulation method is:</div>
<div class="">Error using delaunay<br class="">
At least three input points must be provided to define a triangular mesh. (how can i provide these inputs?)<br class="">
<br class="">
Error in ft_prepare_neighbours (line 275)<br class="">
tri = delaunay(prj(:,1), prj(:,2));<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">3- for the template method I made a custom neighbourhood templated with the file that you have shared on github, it works fine and I even tested it through ft_neighbourplot and the answer was still correct, the output of ft_neighbourplot was:</div>
<div class="">Selected channel CZ, which has 8 neighbours: FC1, FCZ, FC2, C1, C2, CP1, CPZ, CP2<br class="">
</div>
<div class="">But when I tried ft_channelrepair function the output was:</div>
<div class="">Error using cell/unique>celluniqueR2012a (line 249)<br class="">
Elements of cell array input A must be character vectors (row vectors of class char).<br class="">
<br class="">
Error in cell/unique (line 142)<br class="">
[varargout{1:nlhs}] = celluniqueR2012a(varargin{1},logical(flaginds(1:5)));<br class="">
<br class="">
Error in cell/setdiff>cellsetdiffR2012a (line 303)<br class="">

<br class="">

<br class="">
Error in ft_channelrepair (line 204)<br class="">
cfg.missingchannel = setdiff(cfg.missingchannel, data.label, 'stable');<br class="">
<br class="">
the summary of the code is:</div>
<div class="">cfg.channel = {'CZ'};<br class="">
cfg.method = 'template';<br class="">
cfg.layout = 'layout.mat';<br class="">
cfg.template = 'neighbours.mat';<br class="">
</div>
<div class="">neighbours = ft_prepare_neighbours(cfg, data);<br class="">
</div>
<div class="">cfg.badchannel = 'CZ'; </div>
cfg.method = 'average';<br class="">
cfg.neighbours = neighbours;<br class="">
<div class="">data_fixed = ft_channelrepair(cfg,data);</div>
<div class=""><br class="">
</div>
<div class="">Would you mind please helping me with this problem? <br class="">
