Hi!
What is the unit of the y-axis in the mne tutorial on erd/ers
<https://mne.tools/dev/auto_examples/time_frequency/plot_time_frequency_erds.html>
?
Best,

Hz?
Or did you mean the color/z axis? In that case....
The units for EpochsTFR (and thus AverageTFR) depend on the type of
baseline you do:
In the example, they use mode "percent", so it's percent change relative
to the baseline.? I always get this mixed up, but I think "raw" power is
?V^2/Hz
If you look at the info of an MNE object (e.g. epochs.info), then it has
a chs attribute which includes unit information although this may just
be the info for the original measurements (I haven't checked what this
looks like for TFR objects).
Best,
Phillip
