[Mne_analysis] mne.minimum_norm.source_induced_power

[Alexandre Gramfort]

hi,

see

https://github.com/mne-tools/mne-python/blob/master/mne/minimum_norm/time_frequency.py#L369

if no baseline is set then you get raw power.

when using logratio it is the log of the ratios so it's not really dB either.

hope this helps

Alex
