Exclude sulfur atoms from acceptors: If set, sulphur atoms in the acceptors are excluded.
Exclude halogens from acceptors: If set, halogen atoms in the acceptors are excluded.
Display major microspecies: The structure of the major form at the given pH is displayed.
Structure column: The structure column.

Input Ports

: Input table that contains structure in Structure(Mrv, Sdf, Smiles, etc.) format.

Output Ports

: Output table that contains H bond donor/acceptor.
