If I got it right I would suggest this. Try removing parts in your overall structure. For example let's say your system has 3 components water, ATP, TPO. Try removing all but water, try pdb2gmx, all but ATP ( like a sim in vacuo ) try once again pdb2gmx. This will make the "troubled" part "visible". As for the error message, this comes up when you are trying to simulate a molecule that is not included in the default molecule entries. So you will have to include it manually. But when you know which part produces the error then it will be much easier.

I checked all LUE residues (although I have got no residue with 28215089 number) and I found no missing atom N. I am really wondering what should be my next step. could you help me on this? "Fatal error:Residue 28215089 named LEU of a molecule in the input file was mapped to an entry in the topology database, but the atom N used in an interaction of type improper in that entry is not found in the input file. Perhaps your atom and/or residue naming needs to be fixed."
