HeadPosEntry

struct UTILSLIB::HeadPosEntry

A head position entry (time, translation, rotation quaternion).

src/examples/ex_dsp_maxwell/main.cpp

QList<HeadPosEntry> headPos(1); // one position from t = 0: identity rotation, no translation
MaxwellMoveCompParams moveParams;
moveParams.origin = params.origin;
const MatrixXd compensated = MaxwellMovementComp::apply(data, info, headPos, 1.0, moveParams);

QTemporaryDir dir;
const QString posPath = dir.filePath("head.pos"); // same columns as mne.chpi.write_head_pos
const bool posWritten = MaxwellMovementComp::writeHeadPos(posPath, headPos);
const QList<HeadPosEntry> posBack = MaxwellMovementComp::readHeadPos(posPath);
