AMBER Archive (2005)Subject: Re: AMBER: A few question about RDF input preparation
From: Wei Zhang (zweig_at_pku.edu.cn)
Dear Maciej,
If you are using AMBER 8.0, you can use antechamber to parametrize your molecule.

This is this what jumps out after I turn on leap to recording prefiles for 8 - oxodg:
> OXO=loadpdb oxo.pdb
Loading PDB file: ./oxo.pdb
Created a new atom named: OH8 within residue: .R<DG3 1>
Created a new atom named: H within residue: .R<DG3 1>
total atoms in file: 34
Leap added 2 missing atoms according to residue templates:
2 H / lone pairs
The file contained 2 atoms not in residue templates
Since added/missing = extra, there is a high probability
of atoms with 'incorrect' names; you may want to
use addPdbAtomMap to map these names, or change in file
When i change OH8 to O8 or O i have that msg:
OXO=loadpdb oxo.pdb
Loading PDB file: ./oxo.pdb
Added missing heavy atom: .R<DG3 1>.A<C3' 28>
Added missing heavy atom: .R<DG3 1>.A<C2' 30>
Added missing heavy atom: .R<DG3 1>.A<O3' 33>
Added missing heavy atom: .R<DG3 1>.A<C4 27>
Added missing heavy atom: .R<DG3 1>.A<C5 17>
Added missing heavy atom: .R<DG3 1>.A<N3 26>
Added missing heavy atom: .R<DG3 1>.A<N7 16>
Added missing heavy atom: .R<DG3 1>.A<C6 18>
Added missing heavy atom: .R<DG3 1>.A<C2 22>
Added missing heavy atom: .R<DG3 1>.A<O6 19>
Added missing heavy atom: .R<DG3 1>.A<N1 20>
Added missing heavy atom: .R<DG3 1>.A<N2 23>

How should i parametrize this molecule ?
How to make file for ptraj to count RDF betweenoxygen atoms I water box ?
