GROMACS pdb2gmx Warning: Missing Atoms (H and O) in AlphaFold3-Derived TCR–pMHC Structure

GROMACS version: gromacs/2025.3-openmpi-5.0.8-single-rocky8
GROMACS modification: Yes/No
Here post your question

I am new to using GROMACS as I mostly deal with omics data I am using this for my TCR-pMHC structural model from AlphaFold3 and I got this warning message, should i be worried about this? I got this for each of these protein(TCR, peptide, and MHC). How can I resolve this issue? is it something expected?

(WARNING: Residue 1 named GLU of a molecule in the input file was mapped to an entry in the topology database, but the atom H used in an interaction of type angle in that entry is not found in the input file. Perhaps your atom and/or residue naming needs to be fixed.

WARNING: WARNING: Residue 113 named LEU of a molecule in the input file was mapped to an entry in the topology database, but the atom O used in an interaction of type angle in that entry is not found in the input file. Perhaps your atom and/or residue naming needs to be fixed.
