Hi Dirk -

 

I would do this the basic way (because that's the only way I know).  Write a PyMOL script - not a python script, just a series of PyMOL commands.  Like this:

 

(whatever commands you need to load and position your molecules and draw the surfaces)

ray

png movie_001.png

set transparency=0.05, your_ligand

ray

png movie_002.png

set transparency=0.1, your_ligand

 

etc.

 

Setting transparency to 1 is fully transparent, i.e. invisible.  Transparency=0 is opaque.  Once you've run this script, which you can invoke from the PyMOL command line by typing "run my_script", you'll have a series of image files showing the fade.  I recommend using Quicktime Pro to fuse them into a movie - it only costs $30, and it's easy to use for this purpose.

 

Hope that helps,

Matt
