What is the script to access my animation called "run" in my animator controller

I have an animation called Run in my CONTROLLER. How do I call this?

You don’t “call” an animation in an Animator controller - it’s a state machine, so you pass in whatever parameters are required to transition from the current state to the “Run” state, using Animator.SetFloat(), Animator.SetBool() etc.

The Mecanim tutorial video explains this: http://video.unity3d.com/video/7362044/
