I am working on the lipid, whose pdb file I have. While giving command gmx pdb2gmx for converting into gro format following error comes out,
Fatal error:
Residue 'KS7G' not found in residue topology database
Warning: Starting residue KS7G0 in chain not identified as Protein/RNA/DNA.
This chain lacks identifiers, which makes it impossible to do strict
classification of the start/end residues. Here we need to guess this residue
should not be part of the chain and instead introduce a break, but that will
be catastrophic if they should in fact be linked. Please check your structure,
and add KS7G to residuetypes.dat if this was not correct.
Problem with chain definition, or missing terminal residues.
This chain does not appear to contain a recognized chain molecule.
If this is incorrect, you can edit residuetypes.dat to modify the behavior.
8 out of 8 lines of specbond.dat converted successfully
In this case, how can I generate the .gro, topol.top and porse.itb file for lipid?
