 Transforming the force signals from the Force Platform Coordinate System to the Laboratory Coordinate System
-===== C3D Parameter FORCE_PLATFORM:CORNERS =====
+==== C3D Parameter FORCE_PLATFORM:CORNERS ====
 The force platform corners are numbered from 1 to 4. The values are specified in the Laboratory Coordinate System in units consistent with the POINT data. The order is specified by the quadrant numbers in the force platform coordinate system. The order is (+x,+y), (-x, +y), (-x, -y), ( +x, -y).
-===== Computing the Transformation =====
+==== Computing the Transformation ====
 Visual3D calculates the transformation matrix from the force platform coordinate system to the laboratory coordinate system using the force platform corners. This transformation matrix is then used to transform the force vector from the force platform coordinate system (in which it was collected) into the laboratory coordinate system where it is used for the analysis.
