<p>Hi Fawzi,</p>
<p>If you do:<br>
stat = ft_timelockstatistics(cfg,avgP300{:},avgnonP300{:})<br>
It should work.<br>
(this way the contents of each cell is used, instead the cell itself)</p>
<p>Best,<br>
Roemer</p>

Hello again Stephen and for all,<br><br>I could not find out how to enter the following sturct into the ft_timelockstatistics function<br><br>The input is generated using the following loop:<br><br>for i = 1:10<br> cfg = [];<br>

end<br><br><br>Then I use<br><br>cfg = [];<br>cfg.layout = 'CTF275.lay';<br>cfg.method = 'crossvalidate';<br>cfg.design = [ones(10,1); 2*ones(10,1)]';<br>stat = ft_timelockstatistics(cfg,avgP300,avgnonP300);<br>

<br>
Actually, the statistic functions DO accept cellstructures of<br>
datastructures, and what I suggested is therefor very convenient,<br>
especially in that regard.<br>
Please take a look at <a href="http://fieldtrip.fcdonders.nl/walkthrough" target="_blank">http://fieldtrip.fcdonders.nl/walkthrough</a>. I<br>
would recommend walking through it from the beginning, but you could<br>
take a particular look at the statistics section. In there I try to<br>
explain the data structure handling in detail which deals with your<br>
question.<br>
<br>
Cheers,<br>
