Hi!
  I a new user of xplor-NIH. I tried generating the psf file for a protein
using the pdb2psf program. The program gave an error like this:

 %SEGMNT-ERR: attempt to enter duplicate residue      1    PRO
 %SEGMNT-ERR: attempt to enter duplicate residue      16   GLY
 %SEGMNT-ERR: attempt to enter duplicate residue      43   LYS
 %SEGMNT-ERR: attempt to enter duplicate residue      47   ILE
 %SEGMNT-ERR: attempt to enter duplicate residue      48   GLY

This protein is a homodimer with several water molecules. When I submit
the monomeric unit, it does not give an error but is not useful for the
subsequent dynamics run.
I would be grateful if you could help me fix this problem (as I have a
deadline to finish it! :)
Thanks.
Chitra
