i want to know that this loss of atoms does not cause errors in simulation results?
What particular forcefield are you using? Have you noticed any other hydrogen atoms missing? Might it be part of a united atom forcefield model?

In the simulation of KALP15 in DPPC, when we run grompp command, one of the outputs is mdout.mdp. can we use these files for our energy minimization step, after making necessary changes?

I simulated DPPC60%-DMPC40%+protein bilayer system for 100 ns. Now I want to run another simulation for 50 ns on this system. I wonder if its nessecery to use .cpt file from the previous md run. I...
