Re: [AMBER] mismatch NTYPES for mixtures of 2 molecules

And the individual molecules do not have a type in common?

When I generate prmtop and inpcrd for the mixture of these 2 molecules, xleap (tleap) only recognized 7 distinct atom types (NTYPES = 7 in prmtop). It reports NTYPES correctly for individual molecule. I looked at the frcmod file and all atom types have different LJ potential parameters. So I wonder why the discrepancy and if it would affect the simulations at all. I'm using Amber/AmberTool 14.
