hi
I am trying dimer's pdb file with different co-ordinates for both the chains.
when i load this pdb file in xleap it creates a new atom named H within the first residue in the second chain, and it also added a missing atom in last residue of the second chain.
thus file contained 3 atoms not in residue templates.
and when i use the command edit in xleap it shows a dimer with a long bond formed between the first chain C-terminal and second chain N-terminal. Attaching pdb file with mail.

Dear Priya,
I saw your dimer's PDB file. But i guess you don't have a dimer.. the PDB file you have given has same coordinates for both peptide chains...
And the bond thing that you saw using edit in LEaP is I GUESS you are talking about another mistake in the pdb file where a space has come in front of the coordinate values in line number 199-201 (residue 18) so PDB file is read as
ATOM 193 CA ALA 18 2.039 2.062 1.486 1.00 0.00
ATOM 194 CB ALA 18 2.016 1.914 1.453 1.00 0.00
ATOM 195 C ALA 18 2.168 2.084 1.565 1.00 0.00
instead of
ATOM 193 CA ALA 18 20.392 20.621 14.865 1.00 0.00
ATOM 194 CB ALA 18 20.160 19.144 14.539 1.00 0.00
ATOM 195 C ALA 18 21.681 20.840 15.659 1.00 0.00
So i hope you need to have different coordinates to get the chains differently... there would't be any problem from the TER card..
Cheers

I am trying to run a simulation of dimer each chain has 16 residues.In the pdb fileI added TER between the chains but when i use the command edit in xleap there is a bond between the chains. but i want two different chains and non bonded. I am attaching the pdb file with mail.
will anybody tell me the mistake.
Thanks in advance
Priya
