Selective EEG Channel Interpolation

Modified version of EEGLAB's EEG channel interpolation function eeg_interp.m that allows the user to ignore a set of electrodes for interpolating bad channels

Inputs

• eeg_in - EEGLAB EEG data struction to interpolate
• replace_chans - array of channels to replace via interpolation
• ignored_chans - array of channels to ignore as input for interpolation

Outputs

• EEGLAB EEG data structure

Example

eeglab;

%% Load test data set
data_filename = 'S1_Chan.set';
data_filepath = './data/';
eeg_in = pop_loadset('filename', data_filename, 'filepath', data_filepath);

%% Process data
replace_chans     = [1 2 3];                        % Replace these channels via interpolation
ignored_chans     = [4 5 6 7 8 9 10 11   14 15 16]; % Interpolate using electrodes 12 & 13
eeg_out_selective = erplab_selective_eeg_interp(eeg_in, replace_chans, ignored_chans);
