+====== Virtual Lab Direction of Progression Method 1 ======
+This script is explained in the Virtual Lab Direction of Progression tutorial. This script outlines [[Visual3D:Documentation:Modeling:Virtual_Lab:Virtual_Lab_Direction_of_Progression#Method_1|Method 1]].
+Before running this script:
+  * A static trial must be loaded into the workspace
+  * A model template (with modified virtual lab) must be loaded into the workspace
+  * A dynamic trial must be loaded into the workspace
+NOTE: A modified virtual lab follows the same outline as the [[Visual3D:Tutorials:Modeling:Virtual_Laboratory_#Example:_Creating_a_virtual_laboratory_that_changes_with_the_direction_of_walking|Dynamic Virtual Lab]], except instead of using the Lab_X landmark, the Dir_Prog_X landmark is used. An example of this model template can be found here.
