 Hi Modellers! 
I have the pdb format problem. 
I have the same problem with Stephane Coillet-Matillon's error written 
at 19 Mar 2002. 
Eric Feyfant replied it was a chain identifier 
problem.  
 But I don't know how to correct this problem. 
How to solve this problem? 
Thanks, 
Ahrim 
The error messages is like this
