Dear MNE users,
When I managed my EEG data, the results of mne.time_frequency.tfr_morlet (or the other two methods) were an array of power around 1e-7. When being plotted with dB = ‘True’, a good graph was got only when the scale of color is around -150 to -200. However, when I did the psd analysis, the power is around 0-40. What made the differences? Besides, I also did time-frequency analysis with eeglab on matlab, the color scale of dB is around -40 to 40. I cannot understand the differences. Who can explain it, thanks.

Below is the tfr done with matlab(eeglab).
