Hi Javier,

I did tried using the swisspdb for adding missing atoms still am receiving the same error.


The other possibility is that you have a naming mismatch. In this case, pdb2gmx expects to find an atom named "ND1" in your residue but cannot.

    Your PDB structure have probably some missing atoms. Check if this
    is the case for residue nr. 7.

    To solve it you can use an external tool to process your PDB file
    adding the missing atoms. I've used SwissPDB and worked fine.

    Hi Users,

    I did the following step=
     pdb2gmx -ignh -f 1ahw.pdb -o sample.pdb -p sample.top


    and received an error= Atom ND1 not found in residue seq.nr
    <http://seq.nr>. 7 while adding atom.

    I dont understand how do i rectify this.
