  1. Resource Description
    Sinusoidal noise can be a prominent artifact in recorded electrophysiological data. This can stem from AC power line fluctuations e.g. 5060 Hz line noise harmonics power suppliers e.g. in medical equipment fluorescent lights etc. Notch filtering is generally undesirable due to creation of band-holes and significant distortion of frequencies around the notch frequency as well as phase distortion at other frequencies and Gibbs rippling in the time-domain. CleanLine is an EEGLAB plugin which adaptively estimates and removes sinusoidal artifacts from ICA components or scalp channels using a frequency-domain multi-taper regression technique with a Thompson F-statistic for identifying significant sinusoidal artifacts. This approach has been advocated by Partha Mitra and Hemant Bokil Observed Brain Dynamics Chapter 7.3.4. 2007 and CleanLine utilizes modified routines from the Mitra Labs Chronux Toolbox www.chronux.org.
