Error in missing hydrogen atoms

GROMACS version:
GROMACS modification: Yes/No
Here post your question
Is it good to ignore hydrogen using -ignh flag when names do not match?

If only hydrogen names do not match with the force field name, you can use gmx pdb2gmx with the option -ignh to let the tool add the H atoms. Then it is good to check if the H atoms, added by pdb2gmx, corresponds to the wanted one.
