[FieldTrip] Problem matrix dim in ft_timelockanalysis

[Es, M.W.J. van (Mats)]

Hi FieldTrippers,

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:
Index exceeds matrix dimensions.

Error in ft_timelockanalysis (line 278)
    s (:,windowsel) = s (:,windowsel) + dat;            % compute the sum

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.
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.

Best,
Mats van Es
