[FieldTrip] Wavelet- Time frequency analysis

[Bahareh Elahian (belahian)]

Hi All,

I am trying to apply wavelet on my signal to see HFOs.
According to http://www.fieldtriptoolbox.org/tutorial/timefrequencyanalysis
I wrote the following lines but I will get an error that: "the padding that you specified is shorter than the data".
As far as I understood 'maxperlen' is the default.
Any other idea for padding or solving this problem?

cfg= [];
cfg.pad = 'maxperlen';
cfg.method = 'wavelet';
cfg.output = 'pow';
cfg.channel = 'chan 4';
cfg.toi = 1:size(eeg.eeg_data,2);
cfg.foilim  = [80 500];
[freq] = ft_freqanalysis(cfg, data1);




data1 is  my data which I get by applying ft_preprocessing.
