[PyMOL] polar contacts involving F, Cl and S atoms

[Thomas Evangelidis]

Hi Pymol users,

I want to display the polar interactions between some ligands and a  
receptor, but I 'm not quite sure if Pymol can do that for F, Cl or S  
atoms. There's a tutorial on the wiki that explains how to set the  
cutoff distance but that refers only to O and N atoms:

http://www.pymolwiki.org/index.php/Displaying_Biochemical_Properties#Hydrogen_bonds_and_Polar_Contacts

 I was wondering if I can do that by modifying those code snippets. I  
would greatly appreciate any help. Also if someone knows the distance  
H-bond donor and acceptor for F and Cl atoms please tell me. I know  
only  the respective distance for S which is 4 A maximum.

thanks,
Tom
