Thank all of you!
    
I  have not  " change the residue numbers so they do not overlap", so the 
"change chain IDs" doesn't work when I try to change chain ID to an existed 
chain ID.


Edit the PDB file is another good idea but when I have 20 SO4 in 20 chains, 
things become boring.


Best wishes!
