[gmx-users] HA1/HA2 chirality of GLY

Dear GROMACS users,
Is there a convention about the chirality of the HA1 and HA2 hydrogen
atoms in Glycine (relative to the C-alpha)?
Glycine is non-chiral, but if one tries to mutate it to another L amino
acid, one of these hydrogens should be picked as the analog of a
sidechain. Which one is it?
As most PDB files do not contain hydrogens, this question seems to be
about the behavior of pdb2gmx when creating a .gro file with an all-atom
force field (such as opls-aa).
