I have a perl script to do this job. The pdb file should contain your ligand.
Simplest way to run it is "lig_contact file.pdb" If the script does not find the ligand, you can switch to command line options. The script prepares a pymol input file and fires it up to display the interactions. After you close the pymol window you can see the pymol script file. The list of interactions is listed as "distance .?? = (ligand atom), (protein atom)." in this file. The '??' could be cc (hydrophobic interaction) or hb (hydrogen bond).

The only information I need is an output file which lists all amino acids of the target protein which make VDW interactions with the binding small molecule. Thank you very much for your help and recommendations, Mathias
