I am interested in running a simulation of protein-ligand complex to assess
their stability and using the Hydrogen Mass Repartitioning
I am doing so by using the "-heavyh" option of pdb2gmx.
the option will "increase the hydrogen-mass by a factor of 4. This is also
done for water hydrogens to slow down the rotational motion of water. The
increase in mass of the hydrogens is subtracted from the bonded (heavy)
atom so that the total mass of the system remains the same.". See manual:
Now this will do the Hydrogen Mass Repartitioning for the protein only, not
The topology for the ligand is being generated using acpype. I have checked
the mass of atoms for the protein and the ligand and they are different.
How can I fix that for the ligand?
