2 months ago Hey @AnnaPlieva - thanks for trying out the package! I'm not sure what you are trying to do with the aperiodic_mode = 'lorentzian' setting though - that is not an available aperiodic mode. The current options are 'fixed' and 'knee'.
Information on using the available aperiodic modes is available here: https://fooof-tools.github.io/fooof/auto_tutorials/plot_05-AperiodicFitting.html
Hello! Thank you for great toolbox! I want use new 'lorentzian' mode for component aperiodic_mode, but I have an error
fm_lorentzian = FOOOF( aperiodic_mode = 'lorentzian') fm_lorentzian.report(freqs, spectrum, freq_range, plt_log=True)
FOOOF WARNING: Lower-bound peak width limit is < or ~= the frequency resolution: 0.50 <= 0.49 Lower bounds below frequency-resolution have no effect (effective lower bound is the frequency resolution). Too low a limit may lead to overfitting noise as small bandwidth peaks. We recommend a lower bound of approximately 2x the frequency resolution.

I have 1.1.0 fooof version How can I use a new mode?
