[FieldTrip] Fourier analysis units

Dear Casper,

The units of the power spectrum depends on the units of your input data. For example, if your input data is in microvolts, the unit of the power spectrum is microvolts^2 (give that cfg.output=’pow’).

Subject: [FieldTrip] Fourier analysis units

Dear fellow Fieldtrippers,

I've made some Fourier analyses using ft_freqanalysis with cfg.method = 'mtmfft', and found something worth reporting. However, Fieldtrip does not report the units.

Looking at conversations in the Fieldtrip discussion archive, it would seem this question has either been sidestepped or not answered in the past, so I'd like to ask this question again.

Does anybody know?

Best regards,
