I have a 5 similar domains (struct.pdb) aligned on another one 
(rcsb.pdb).  I made a copy of one of them and translated it 37 
angstroms to the right. translate [37, 0, 0 ].
But I did not get a simple translation.  The two molecules end up 
having a rotation between them.
Here's the script. I need an "origin" command or other...?
thanks,
Dave
