Hi Dear Users!
I'm Using MMB to produce initial structures for my simulations.
This program creating a .pdb file in output.
The output file containing Hydrogen atoms that are not recognized by gromos53a5. I want to edit my pdb file but I can't find anything about "hydrogen types in gromos"!
any suggestion?


The Gromos force fields are united-atom, so most H atoms are not used. Aromatic hydrogens are type HC and polar hydrogens are type H.

If you're trying to run your structure through pdb2gmx and it's complaining, use -ignh and only necessary hydrogens will be built back on.
