Re: [Open Babel] Adding hydrogens before docking

Thanks - Vina is being used, and if all H are not added before energy minimization, it appears that results are off (e.g. long CH2 chains will look like a loose rope). Yes, Vina only leaves polar H in the resulting pdbqt files. Get Outlook for Android On Sat, Nov 3, 2018 at 6:38 AM -0

Hi, This is highly dependent on docking software. Autodock Vina requires only polar hydrogens, but others will differ. Best, Maciek sob., 3 lis 2018, 11:28: Noel O'Boyle napisał(a): > You need to add all hydrogens. I have never understood why those options > are provided. > > On Thu, 1 Nov 20

You need to add all hydrogens. I have never understood why those options are provided. On Thu, 1 Nov 2018, 19:41 Leif Peterson Before performing ligand energy minimization then docking with receptors, > I am adding hydrogens to ligands via the syntax: > > Addhydrogens(False, False); > > I am pret

Re: [Open Babel] Stripping salts (counter ions) before docking

Think about cells or stomachs or whatever having a certain pH due to the presence of acids and bases. Your molecule will be protonated according to this pH. On Thu, 1 Nov 2018, 19:52 Leif Peterson For stripping the counter ion of a salted ligand, I am basically using the > larger smiles string aft
