Hi Mats,
<div>Based on your description I suspect an issue with floating point numerical round off. I would assume that the length of your trials is fixed and the time axis supposed to be equal across trials?</div>
<div>Could you try and do data.time(1:end) = data.time(1); and report back whether the problem persists (or vanishes)?</div>
<div>Best,</div>

<div style="direction: ltr; font-family: Tahoma; font-size: 10pt;">Hi FieldTrippers,
<div><br>
</div>
<div>I want to apply a support vector machine (SVM) on small timewindows of my data, which means I loop ft_timelockanalysis and ft_timelockstatistics over time. However, for some timepoint I get the following error:</div>
<div>
<div><i>Index exceeds matrix dimensions.</i></div>
<div><i><br>
</i></div>
<div><i>Error in ft_timelockanalysis (line 278)</i></div>
<div><i> s (:,windowsel) = s (:,windowsel) + dat; % compute the sum</i></div>
</div>
<div><br>
</div>
<div>I tried to look into the error, and I saw that for some timewindows 'windowsel' and 'dat' are a 1x4 vector, whereas 's' is a 1x3 vector. I couldn't find why this mismatch occurs so any help is appreciated.</div>
<div>I also tried older versions of this function and I got the same error. I am using the latest fieldtrip on matlab2015a on the cluster.</div>
<div><br>
</div>
<div>Best,</div>
