I'm using fieldtrip-20110315 on a Mac Pro running MATLAB 7.11 and OS X 10.6.6. ft_freqanalysis should not run with cfg.output='fourier and cfg.keeptrials='no'. Das ist verboten. You need the individual trials for later processing of the complex Fourier spectra. Something should be added around line 300 of ft_freqanalysis to make sure that cfg.keeptrials='yes' (and cfg.keeptapers='yes') Cheers, Matt

I changed the code. Don't remember exactly what lines. Could you check whether it works for you? Thanks, JM

Yep, you fixed it. output='fourier' only works with keeptrials='yes' and keeptapers='yes', which is the proper behavior.

Possible caveat I just thought of: When dealing with wavelet data should it matter if one sets keeptapers='yes' or keeptapers='no'? My limited knowledge about this makes me think that there are no tapers in wavelet analyses and so the value of keeptapers wouldn't matter, but maybe I'm wrong.
