This pipeline command does what its name suggests: it transforms signals from one coordinate system to another. A popular use case for this command is to transform signals from the Lab Coordinate System to a Virtual Lab Coordinate System, for example when a participant turns around and walks back to their initial point.

Moving force plates can be modelled using a process that leverages the Transform_Data_Coordinate_System command. The premise is that once you create segments representing the force platform and move it to the lab origin (aligned with the lab coordinate system), you transform your FORCE, COFP and FREEMOMENT signals from the force platform at the origin to the moving platforms.

! Transform COFP - Translation as well (not Orientation only)
