Static Methods​

makeCorticalMap(fwd, inv, info)​

Create a cortical mapping matrix that transforms sensor-level data to source space.

The mapping is computed as: M = inv_kernel * fwd_gain^T

where inv_kernel is the inverse operator kernel and fwd_gain is the forward solution gain matrix.

Parameters:

  • fwd : const MNEForwardSolution & The forward solution containing the gain matrix.

  • inv : const MNEInverseOperator & The inverse operator (must have been prepared / have a kernel).

  • info : const FiffInfo & The measurement info for channel selection.

Returns:

  • Eigen::MatrixXd — The cortical mapping matrix (nSources x nSources).
