Dear Andrea -
You should try using the Gerstein Morph Server:
http://www.molmovdb.org/molmovdb/morph/
The core algorithm uses CNS, so if your structure is parsed properly by
CNS, it should emerge from the server looking OK. You'll get a small movie
back from the server, and you can also ask it to send you the PDB files
used for each frame, so you can make your own movies in Pymol.
For making movies in complicated situations like this, I've usually used
script files to explicitly define each frame of the movie:
load file1.pdb
(rendering commands)
ray 2400,2400
png frame1.png
delete file1
load file2.pdb
etc...
You get a long script file, but you can use a text editor to copy & paste
the text blocks.
Hope that helps,
Matt
