Electrode Montage Set

Channel labels can now be imported from an electrode montage file. Sometimes EEG files don´t have the electrode name set as the channel label.

e.g. channel names ['Channel 1', 'Channel 2', 'Channel 3', 'Channel 4'...etc]

A path can be specified to a electrode montage set, where at least two columns are needed.

• Column with the channel names or numbers in the original EEG.
• Column with the electrode names for the corresponding channel.

Once its loaded the channel labels will be updated.

e.g. channel names ['Fp1', 'Fp2', 'AF7', 'AF3'...etc]

   G.load_data(path, exclude = [None], electrode_montage_path = None)

Parameters:

• path: Required | str

  Path to the EEG file.

• exclude: Optional - Default = [None] | list of str

  Channel names from the EGG to be excluded from the analysis.

• electrode_montage_path: Optional - Default = None | str

  Path to the electrode montage file.

Example:

   G = eegraph.Graph()
   G.load_data(path= "eeg_sample_1.edf", exclude = ['EEG TAntI1-TAntI', 'EEG TAntD1-TAntD', 'EEG EKG1-EKG2'], electrode_montage_path = 'electrodemontage.set.ced')
