CCL:hwo to get the CHARMM topology and parameter files



 Dear sir,
 
I have a problem when I use NAMD program. I just try the example"BPTI" in the user guide. However I couldn't find the CHARMM topology and parameter files on the website http://www.pharmacy.umaryland.edu/faculty/amackere/research.html. Maybe the relevant link had changed.
 Could you please tell me where I can find them? Thank you very much!
 Yours Sincerely
 
Ying Xiong
