[Eeglablist] CleanLine plugin not removing 60hz noise?

[Charisse Pickron]

Thank you for this information. I had seen a thread about this other
cleanline, but wasn't sure if it could be used outside of the PREP pipeline
as I'm working on my own pipeline. I'll be on the lookout for announcements
related to the cleanline bug fixes.
Thank you and best regards,
-Charisse
