mda equivalent of Rdkit's addHs

[corey-taylor2]

G'day all,

Looking to extract a ligand and surrounding residues from a Universe but then to cap valences in a manner similar to Rdkit's addHs module to feed into some qchem workflows. Directly saving the selection as a pdb shows there are indeed unsatisfied valences.

I've Googled and searched and can't find a way to do this, so either it's so blindingly obvious that this topic will prove a useful reminder to others.... Or it's not as straightforward as I'd like it to be. Anyone have some code laying around to achieve my dreams? Cheers all.
