Hi PyMOL Community,

I have a trajectory file loaded into PyMOL but I would like to play the movie in reverse order.  Is there a way to achieve this within PyMOL?  I know that I could do this by outputting the states as PNG files and then reversing them in an external program but I would like to be able to easily do this within PyMOL's visualization environment.

The reason why I want to reverse the trajectory is because it was generated from Principal Component Analysis and then the original trajectory was projected onto one of the eigenvectors in order to see the motions involved in a transition.  Unfortunately, the direction that was produced is opposite of what I actually observe.

Thanks

Sean
