Raw to_data_frame Object

Hi everyone, I have a question about the to_data_frame() method for raw objects. Does the data in this dataframe describe the frequencies or the amplitudes at each time point?

If this dataframe describes the amplitudes at each time point, are there other methods in which I can obtain the frequencies at each time point?


  • MNE version: 1.0.3
  • operating system: Windows 11

Thank you so much.

raw.to_data_frame() gives signal amplitudes.

for frequencies you can do

spectrum = raw.compute_psd()
