CCL: Where to download pdb ligand files?



 Sent to CCL by: "Steven  Z" [yzhao++mail.sioc.ac.cn]
 Hi, CCLers
 I'm writing a PDB converting program and I need some diversity structures to
 test it. I know that there are about 6400 ligands in Protein Data Bank. Can
 anybody tell me where can I download those PDB ligand files?
 Thanks in advance.
 Best wishes.
 Steven
