conpy.forward_to_tangential

conpy.forward_to_tangential(fwd, center=None)

Convert a free orientation forward solution to a tangential one.

Places two source dipoles at each vertex that are oriented tangentially to a sphere with its origin at the center of the brain. Recomputes the forward model according to the new dipoles.

Parameters:

fwdinstance of Forward

The forward solution to convert.

centertuple of float (x, y, z) | None

The carthesian coordinates of the center of the brain. By default, a sphere is fitted through all the points in the source space.

Returns:

fwd_outinstance of Forward

The tangential forward solution.
