Ah. I just looked through the gen3d code to see why this is happening: > pmol->AddHydrogens(false, true); // Add some hydrogens before running MMFF So if you're using code, you want to run gen3d and *then* add hydrogens again to re-protonate the OH with existing versions of libopenbabel. I'm not sure if this is the appropriate default for gen3d, since it might violate the principle of least surprise. (Certainly it surprised you.) Thoughts? Should the default gen3d use the pH model corrections for adding hydrogens? -Geoff ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
