Hello Everyone

I have got a doubt relating to making PYMOL MOVIE.
I have like 10,000 PDBs named x_1.pdb .....x_23.pdb and so on

I want to make a movie which essentially should act as the slideshow from x_1.pdb to ..... x_9999.pdb

This would show,kind of show the MD simulations for the protein. 


1 . I guess I would have to align the pdbs wrt some source to actually be able to see the real MD changes in the succeeding pdb structures.
2. Please show me some commands on how I can achieve all of above.

Thanks again
