11.3.1 animate

  These commands control the animation of a molecular trajectory and are used to read and write animation frames to/from a file or Play/Pause/Rewind a molecular trajectory.

• dup [ frame number ] molId: Duplicate the given frame (default ``now'') of molecule molId and add the new frame to this molecule.
• forward: Play animation forward.    
• for: Same as forward.
• reverse: Play animation backward.
• rev: Same as reverse.
• pause: Pause animation.  
• prev: Go to previous frame.
• next: Go to next frame.
• skip n: Set stride to n+1 frames.
• delete all: Delete all frames from memory.  
• speed n: Set animation speed to n.  
• style once: Set to play animation once.
• style loop: Set to loop through animation continuously.
• style rock: Set to play animation forward and back continuously.
• styles: Return a list of the available styles.  
• goto start: Go to first frame.  
• goto end: Go to last frame.  
• goto n: Go to frame n.  
• read filename [beg nb] [end ne ] [skip ns] [molecule_number]: Read data for molecule_number from filename, beginning with frame nb, ending with frame ne, with a stride of ns+1.    
• write filename [beg nb] [end ne ] [skip ns] [molecule_number]: Write data from molecule_number to filename, beginning with frame nb, ending with frame ne, with a stride of ns+1.      
• delete [beg nb] [end ne] [skip ns] [molecule_number]: Delete data for molecule_number, beginning with frame nb, ending with frame ne, with a stride of ns+1.    
• readdel filename [beg nb] [end ne] [skip ns] [molecule_number]: Read data for molecule_number from filename, beginning with frame nb, ending with frame ne, with a stride of ns+1, overwriting existing data.
