Muscle artefact removal in Resting State EEG

[AR6789 (Aron)]

I am setting up a preprocessing pipeline for Resting State EEG and want to remove the muscle artifacts out of the data. If i run ICA.find_muscle_bads it suggests that i need to remove 13 of my 20 components. Is there someone here that knows which threshold of an ICA muscle component is really seen as a muscle artifact? Now the threshold of the score is 0.15, can i increase this to 0.4?
I don’t want to lose all these components.

Thank you in advance!!

ps: I am using mne version 1.4.0

That will always depend on the data, you will have to perform visual inspection of your data and see which thresholds work for you.

Try to work through the tutorial: Annotate muscle artifacts — MNE 1.6.0 documentation

Other than that, try to get some colleagues to look at your data.
