does mne-python support or have plans to support events per channels?

I’m trying to re-write HFO (high-frequency-oscillation) algorithms proposed in the literature for iEEG data (implemented in matlab currently), which define these “HFO” events per channel. I am doing it for a comparative analysis, but I wanted to make it sklearn and mne-python compatible since I can see it being very useful for ppl to switch over from the bane of matlab.

This rewrite is useful for my own research, but I can see it being useful in general to mne folks. However, HFOs inherently are “specific channel events”, whereas the current Annotations data structure only supports “non-specific channel events”.

at this stage no. I would use annot description to document the channels covered
