How to use the Functions

in this example we assume EEG is you loaded dataset:

to open the plotter and check e.g. for artifacts and hide bad channels use the code

` EEG = csc_eeg_plotter(EEG); `

to change the hidden channels to bad channels use

` EEG.bad_channels{1} = EEG.hidden_channels; `

to reject/delete channels with artifacts

` EEG = pop_select(EEG, 'nochannel', EEG.bad_channels{1}); `

if you have run e.g. ICA on your dataset and want to look/remove components

open the plotter and also the component plot for each channel

` csc_eeg_plotter(EEG); EEG.good_components = csc_component_plot(EEG); `

now to remove the marked bad components and automaticaly change the local eeg variable use

` EEG = pop_subcomp( EEG , find(~EEG.good_components)); EEG = eeg_checkset(EEG); `
