[gmx-users] Coordinate file does not match topology

[Sheyore Omovie]

Thanks guys,
I've finally resolved it.
I think gromacs has an issue with the naming convention used in the pdb file 
I created with pymol.
So I started all over again, stripped the pdb file of its H-atoms. That way, 
both pdb2gmx and grompp worked just fine. pdb2gmx added the H-atoms I need 
in the structure.
Rgds
