How to select particular set of channels?

I want to plot PSD from occipital region

You can use mne.read_selection(), as pointed out in this posting:

Vectorview channel groups

Thanks. I think mne.selection.read_selection is what I remembered

So what you’d do is something like:

picks = mne.read_selection('occipital', info=raw.info)
raw_occipital = raw.copy().pick(picks)
raw_occipital.plot_psd()
