Hello Roemer,<div><br></div><div>Here's the cfg's and output from calls to ft_freqanalysis with method='wavelet' and the subsequent call to ft_singleplotTFR and the resulting error. The imagesc command will however plot the data at that channel imagesc(squeeze(wvpow.powspctrm(strmatch('A177',label),:,:))) Thanks for any help!</div>

<br>
Could you give some more information on the errors? Could you also
post your cfg's? That will help in finding and fixing the bug.
What FieldTrip version are you using?<br>
<br>
Best,<br>
