Zapline-plus is a wrapper for Zapline that automatically removes spectral peaks like line noise from your data while ensuring minimal negative impact, preserving both the non-noise spectrum and the data rank. It searches for noise frequencies, divides the data into spatially stable chunks, and adapts the cleaning strength automatically. A detailed plot is created.
If you just want to download the package and use Zapline-plus with any data matrix, you can feed that data and the sampling rate directly in like this:
cleanedData = clean_data_with_zapline_plus(data,srate);Or if you live in the EEGLAB universe, you can install Zapline-plus via the EEGLAB plugins manager and then run the cleaning either via the Tools GUI or in the command line like this:
EEG = clean_data_with_zapline_plus_eeglab_wrapper(EEG,struct('noisefreqs','line')) % specifying the config is optionalPlease check out the wiki articles for a detailed guide on how to use Zapline-plus and how to interpret the plot.
