Montage Constants#

This section documents the standard montage mappings and constants used in AutoClean for EEG channel locations and naming.

Constants#

autoclean.utils.montage.VALID_MONTAGES: list#

List of valid montages loaded from montages.yaml in the configs directory. These montages are verified to work with AutoClean’s processing pipeline.

autoclean.utils.montage.GSN_TO_1020_MAPPING: dict#

Standard 10-20 to GSN-HydroCel mapping based on official EGI GSN-HydroCel channel maps. This dictionary maps standard 10-20 system channel names to their corresponding GSN-HydroCel electrode numbers.

The mapping includes:

  • Frontal midline electrodes (Fz, FCz, Cz)

  • Left/Right frontal electrodes (F3/F4, F7/F8, FC3/FC4)

  • Left/Right central/temporal electrodes (C3/C4, T7/T8, CP3/CP4)

  • Parietal midline electrodes (Pz, POz)

  • Left/Right parietal/occipital electrodes (P3/P4, P7/P8, O1/O2)

autoclean.utils.montage._1020_TO_GSN_MAPPING: dict#

Reverse mapping from GSN-HydroCel to 10-20 system. This is automatically generated from GSN_TO_1020_MAPPING and provides the inverse lookup (GSN electrode number to 10-20 name).
