Detailed Description

Background worker for computing sensor field mapping matrices.

RtSensorInterpolationMatWorker computes dense sensor-to-surface field-mapping matrices in a background thread.

This worker encapsulates the expensive FieldMap::computeMegMapping() and computeEegMapping() calls that were previously performed synchronously on the main thread inside BrainView::buildSensorFieldMapping().

The worker stores all relevant parameters (evoked info, surface geometry, transforms, etc.) and recomputes the mapping matrices when any parameter changes. It emits newMappingMatrixAvailable() when a new matrix is ready.

Thread-safety: all public setters are mutex-protected and schedule a recomputation via the computeMapping() slot.

Member Function Documentation

computeMapping

void RtSensorInterpolationMatWorker::computeMapping ( )

slot

Compute the sensor-to-surface mapping matrices. This slot can be called directly or connected to a signal. The computation reads the stored parameters and builds dense mapping matrices via FieldMap::computeMegMapping() / computeEegMapping().

Definition at line 179 of file rtsensorinterpolationmatworker.cpp.

newEegMappingAvailable

void DISP3DRHILIB::RtSensorInterpolationMatWorker::newEegMappingAvailable ( const QString & surfaceKey, QSharedPointer< Eigen::MatrixXf > mappingMat, const QVector< int > & pick )

signal

Emitted when new EEG mapping data is available.

Parameters

[in]	surfaceKey	The surface the mapping targets.
[in]	mappingMat	Dense mapping matrix (nVerts x nChannels).
[in]	pick	Channel indices picked for this mapping.

newMegMappingAvailable

void DISP3DRHILIB::RtSensorInterpolationMatWorker::newMegMappingAvailable ( const QString & surfaceKey, QSharedPointer< Eigen::MatrixXf > mappingMat, const QVector< int > & pick )

signal

Emitted when new MEG mapping data is available.

Parameters

[in]	surfaceKey	The surface the mapping targets.
[in]	mappingMat	Dense mapping matrix (nVerts x nChannels).
[in]	pick	Channel indices picked for this mapping.

setBadChannels()

void RtSensorInterpolationMatWorker::setBadChannels

(

const QStringList &

bads

)

Set the bad channels. Triggers recomputation if changed.

Parameters

[in]

bads

List of bad channel names.

Definition at line 171 of file rtsensorinterpolationmatworker.cpp.

setEegSurface()

void RtSensorInterpolationMatWorker::setEegSurface	(	const QString &	surfaceKey,
		const Eigen::MatrixX3f &	vertices )

Set the surface geometry used for EEG field mapping.

Parameters

[in]	surfaceKey	The key identifying the surface.
[in]	vertices	Vertex positions (nVerts x 3).

Definition at line 160 of file rtsensorinterpolationmatworker.cpp.

setEvoked()

void RtSensorInterpolationMatWorker::setEvoked

(

const FIFFLIB::FiffEvoked &

evoked

)

Set the evoked data that contains channel info and sensor definitions.

Parameters

[in]

evoked

The evoked dataset.

Definition at line 118 of file rtsensorinterpolationmatworker.cpp.

setMegFieldMapOnHead()

void RtSensorInterpolationMatWorker::setMegFieldMapOnHead

(

bool

onHead

)

Set whether the MEG field should be mapped onto the head (BEM) surface rather than the helmet surface.

Parameters

[in]

onHead

True to map onto head.

Definition at line 137 of file rtsensorinterpolationmatworker.cpp.

setMegSurface()

void RtSensorInterpolationMatWorker::setMegSurface	(	const QString &	surfaceKey,
		const Eigen::MatrixX3f &	vertices,
		const Eigen::MatrixX3f &	normals,
		const Eigen::MatrixX3i &	triangles )

Set the surface geometry used for MEG field mapping. This must include vertex positions and normals (for MEG).

Parameters

[in]	surfaceKey	The key identifying the surface.
[in]	vertices	Vertex positions (nVerts x 3).
[in]	normals	Vertex normals (nVerts x 3).
[in]	triangles	Triangle indices (nTris x 3).

Definition at line 145 of file rtsensorinterpolationmatworker.cpp.

setTransform()

void RtSensorInterpolationMatWorker::setTransform	(	const FIFFLIB::FiffCoordTrans &	trans,
		bool	applySensorTrans )

Set the head-to-MRI coordinate transform.

Parameters

[in]	trans	The transform.
[in]	applySensorTrans	Whether to apply the transform.
