Hi MNE Experts,

I am using the python function source_induced_power, having the following github code:

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

What are the units of the power output values? Are they in dB? It seems that power is in dB only when the values are baseline corrected with a rescaling option of ?log ratio?.

Can you please confirm if this is actually the case since this is not documented?

Thanks so much,

Charmaine

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
