Detailed Description

Top-level driver for MEG/EEG forward-solution computation.

Implements the forward-solution computation driver.

ComputeFwd is the worker/factory that takes a ComputeFwdSettings, initialises all required data structures (coil definitions, BEM or sphere model, source spaces, compensation data, coordinate transforms) and assembles the MEG/EEG lead-field matrix G one dipole column at a time. The computed MNEForwardSolution is returned by calculateFwd; updateHeadPos rebuilds only the MEG block after a new device-to-head transform.

Constructor & Destructor Documentation

◆ ComputeFwd()

ComputeFwd::ComputeFwd ( std::shared_ptr< ComputeFwdSettings > pSettings )

explicit

Constructs a ComputeFwd and initialises all data structures needed for the forward computation according to pSettings.

Parameters

[in] pSettings Shared pointer to the forward computation settings.

ComputeFwd::~ComputeFwd ( )

virtual

Destructor.

Member Function Documentation

◆ calculateFwd()

std::unique_ptr< MNEForwardSolution > ComputeFwd::calculateFwd ( )

Perform the forward calculation.

Returns: The computed forward solution, or nullptr on error.

Definition at line 507 of file compute_fwd.cpp.

◆ updateHeadPos()

bool ComputeFwd::updateHeadPos	(	const FIFFLIB::FiffCoordTrans &	transDevHead,
		MNELIB::MNEForwardSolution &	fwd )

Update the head position with a new device-to-head transform and recompute the MEG portion of the forward solution.
