Scripting & Command Line

---

You can automate data import using the pop_WearableSensing function in your MATLAB scripts.

Basic Usage

To import a single file:

EEG = pop_WearableSensing('C:\Path\To\Your\File.csv');

Arguments

You can pass additional arguments as name-value pairs.

Argument	Type	Default	Description
channels	Integer Array	All	Vector of channel indices to import. Ex: [1 3 5]
blockrange	[Min Max]	All	Time range in seconds to import. Ex: [0 60]
highpass	Float	Empty	Highpass filter cutoff frequency in Hz.
lowpass	Float	Empty	Lowpass filter cutoff frequency in Hz.
reref	String	‘Linked Ears’	Reference scheme: 'Linked Ears' or 'Hardware Reference'
removeaux	String	‘on’	Remove DSI-24 Aux channels? 'on' or 'off'
importevent	String	‘on’	Import trigger events? 'on' or 'off'

Example

Import the first 60 seconds of data, apply a 1Hz highpass filter, and keep the hardware reference:

EEG = pop_WearableSensing('subject01.csv', ...
    'blockrange', [0 60], ...
    'highpass', 1.0, ...
    'reref', 'Hardware Reference');

Batch Processing

The pop_WearableSensing function operates on a single file at a time. To process multiple files in a script, use a standard MATLAB for loop.

Example: Import all CSVs in a folder

% Define your data directory
dataDir = 'C:\MyExperiments\Study1\';
files = dir(fullfile(dataDir, '*.csv'));

% Loop through each file
for i = 1:length(files)
    fileName = files(i).name;
    fullPath = fullfile(dataDir, fileName);
    
    fprintf('Importing %s...\n', fileName);
    
    % Import the data
    EEG = pop_WearableSensing(fullPath, ...
        'highpass', 0.1, ...
        'lowpass', 70);
        
    % Assign a set name
    EEG.setname = fileName;
    
    % Store in ALLEEG (standard EEGLAB workflow)
    [ALLEEG, EEG, CURRENTSET] = eeg_store(ALLEEG, EEG, 0);
end
