RtInvOp

Namespace: RTPROCESSINGLIB  ·  Library: DSP Library

#include <dsp/rt_inv_op.h>

class RTPROCESSINGLIB::RtInvOp

Real-time inverse dSPM, sLoreta inverse operator estimation.

Controller that manages RtInvOpWorker for online inverse operator updates.

src/examples/ex_dsp_rt/main.cpp
RtInvOp rtInvOp(rawInfo, fwd); // MEG-only operator, loose 0.2, depth 0.8
MNEInverseOperator inverse;
bool inverseDone = false;
QObject::connect(&rtInvOp, &RtInvOp::invOperatorCalculated, [&](const MNEInverseOperator& op) {
    inverse = op;
    inverseDone = true;
});
rtInvOp.append(noiseCov); // e.g. each new RtCov estimate

Public Methods​

RtInvOp(p_pFiffInfo, p_pFwd, parent)​

Creates the real-time inverse operator estimation object.

Parameters:

  • p_pFiffInfo : QSharedPointer<FiffInfo> & Fiff measurement info.

  • p_pFwd : QSharedPointer<MNEForwardSolution> & Forward solution.

  • parent : *QObject ** Parent QObject (optional).

~RtInvOp()​

Destroys the inverse operator estimation object.

append(noiseCov)​

Slot to receive incoming noise covariance estimations.

Parameters:

  • noiseCov : const FiffCov & Noise covariance estimation.

setFwdSolution(pFwd)​

Slot to receive incoming forward solution.

Parameters:

restart()​

Restarts the thread by interrupting its computation queue, quitting, waiting and then starting it again.

stop()​

Stops the thread by interrupting its computation queue, quitting and waiting.

Example​

Used in examples​
