<p class="MsoNormal">Hi Jan-Mathijs,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you for your help. I went in to have a look at what is going on inside those loops and found that the error is occurring in iteration 6, when the field source.trial(1).label is concatenated. It uses the indexes for the big data cells
(ori, mom & filter) which clearly doesn’t work on the small cell with the labels. This seems to me that this is a bug.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I added a piece of code in front of the loop that was giving the error (before line 177 and make the if and elseif.<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:7.5pt;font-family:Courier"> <span style="color:blue">

elseif</span> iscell(dat)<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This worked to circumvent the problem. However, I do get the warning that the dimord of “ori” and “df” could not be determined. When using this cleaned source struct in source statistics I get further errors.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It looks like an issue with how the source struct is built by the source analysis function with trials, and lateron needs to be restructured. SO I would like to know what is the needed structure for ft_sourcestatistics, so we can adjust
the code correctly.<o:p></o:p></p>

<p class="MsoNormal">My recommendation here would be to use the matlab debugger and inspect the cause of the error. The ‘Index exceeds array bounds’ is quite a clear error message, and suggests that there is a mismatch between the number of elements in dat/val,
and the numbers represented in indx(k).<o:p></o:p></p>
