#include <utils/standard_montage.h>

class UTILSLIB::StandardMontage

Standard EEG montage with named electrode positions.

src/examples/ex_utils/main.cpp
const QList<ElectrodePosition> montage1020 = StandardMontage::getMontage(StandardMontage::System::Standard_1020);
Vector3d cz;
const bool found = StandardMontage::findElectrode("Cz", cz); // mne's standard_1005 positions, metres, MNI frame

Static Methods​

getMontage(system)​

Get a standard montage by system name.

Parameters:

  • system : System The montage system.

Returns:

getElectrodeNames(system)​

Get electrode names for a standard montage.

Parameters:

  • system : System The montage system.

Returns:

  • QStringList — List of electrode names.

findElectrode(name, pos)​

Look up a single electrode position by name.

Searches every position of the standard_1005 table, including the fiducials Nz, LPA and RPA.

Parameters:

  • name : const QString & Electrode name (case-insensitive).

  • pos : Eigen::Vector3d & Position if found.

Returns:

  • bool — true if found.

electrodeCount(system)​

Get the number of electrodes in a montage.

Parameters:

  • system : System The montage system.

Returns:

  • int — Number of electrode positions defined for the montage.
