The difference between source_band_induced_power and apply_inverse_tfr_epochs

Hello dear MNE experts!
I am struggling with understanding the difference between the following functions:

  1. mne.minimum_norm.apply_inverse_tfr_epochs()
  2. mne.minimum_norm.source_band_induced_power()

As far as I understand, the former takes EpochsTFR as input and returns a list of stcs for each frequency and epochTFR. At the same time, the latter function seems to take epochs and specified frequency band (e.g., dict(alpha=[8, 13]), then performs the time-frequency decomposition to the provided epochs and returns stcs for each specified frequency band. Additionally, a label to estimate power can be used, otherwise, all vertices will be used for the analysis.

The question is: if I use the same method for both functions and the same frequency band to compute TFR, will the resulting stcs be the same?

Sorry, I am not an expert in the field, and could not find answers to these question in the MNE github repository. If anyone could explain it to me or share relevant sources, that would be great!

Thank you in advance!

Best regards,
Maria
