[gmx-users] RE: Converting from AMBER to GROMACS

The "Long Bond" warnings exists due to the way I changed some names
in the PDB file. It is not a "pdb2gmx" problem nor a PDB problem. It was my
fault. But the question is there: how can I get a correlation betweeb the
old restart file and the new PDB?
