class INVLIB::InvSensorSet

Stores MEG sensor geometry (positions, orientations, weights, coil count) for a single sensor type.

src/examples/ex_inv_hpi/main.cpp
InvSensorSetCreator creator; // reads resources/general/coilDefinitions/coil_def.dat
QList<FiffChInfo> megChannels;
for (const FiffChInfo& ch : info->chs) {
    if (ch.kind == FIFFV_MEG_CH)
        megChannels << ch;
}
const InvSensorSet sensors = creator.updateSensorSet(megChannels, Accuracy::high); // integration points per coil
