When opening the CMO file, notice that the Virtual Lab segment is aligned with the principal axes of the lab. The scripts for Method 1 and Method 2 will update the alignment of the Virtual Lab segment so that the axes is aligned with the direction of progression. Method 3 calculates the joint angles manually, so it is not necessary to update the alignment of the Virtual Lab since it is not used. Each of the following methods can be used with the [[https://www.has-motion.com/download/examples/DirectionOfProgression/DOP_SampleFiles.zip|sample data files]].

 This method creates a Virtual Lab segment that follows the general orientation of the Pelvis (or any segment) but keeps the transverse plane parallel to the lab floor. In other word, this method constrains the Virtual Lab to only rotations around the vertical axis based on the Pelvis segment. This method thus allows to compute variables using the instant direction of progression. This method creates a Virtual Lab segment that follows the general orientation of the Pelvis (or any segment) but keeps the transverse plane parallel to the lab floor.
