info about plot_psd on eopched data

Dear all,

I am using the plot_psd function to plot the power for different frequency bands in different conditions. This works fine, but I wonder how the function extracts power information, exactly? I understand that it computes the power for each epoch and gives the average in the output. But does it use a short-time Fourier transform with overlapping segments? How does the function deal with the "edges issue"? Is there any specific documentation on this function that I can find online?

Thanks in advance,

Davide

hi,

it's using multitapers

internally it's
http://www.martinos.org/mne/dev/generated/mne.time_frequency.psd_multitaper.html

I agree that doc at
https://martinos.org/mne/stable/generated/mne.Epochs.html#mne.Epochs.plot_psd
should be clarified.
