[FieldTrip] simple sinusoidal signal as input to wavelet analysis

[McGowin, Inna]

Hello Maria,
I have an MEG data set measured from a current dipole energized by a
generator with a sinusoidal signal at 7Hz. All waveforms look pretty
sinusoidal on all channels. I was able to import the data into Matlab too.
I can share the data if it helps.

Thanks,
Inna
