Ignoring & Selecting Different Frequency Ranges

[TomDonoghue]

There has been some discussion of either adding exclusion zones to model fitting, and/or fitting different frequency ranges for aperiodic & periodic fitting. This is something that could be broadly interesting, and useful, but I think it needs a bit more looking to figure if and how to best adopt it.

Things to keep in mind:

• If there are 'gaps' in the fit spectrum, we have to consider if and how to fit peaks that might be next to, or overlap with, these regions.
  • Related: we have procedures for dealing with peaks near edges, that might need to be extended
• The logic of the model recommends that to fit either periodic or aperiodic requires dealing with / fitting the other component. Though I think there could be reason and utility to fit different ranges / exclude regions, I don't think we want to lean too far into fitting these as separate processes.

Related prior discussions:

• Exclude a frequency regions for fitting
  • This discussion led to adding the interpolate_spectrum function
  • Exclude frequency range of line noise when fitting slope fooof#20
• Add flexibility in choosing frequency regions for different components
  • Adds more flexibility in the aperiodic/oscillatory fitting fooof#147
