Re: [Rdkit-discuss] mmFF minimization in context of two ligands/binding pocket

2016-04-01 Thread Paolo Tosco
Dear Steven, just to add up a small bit to Maciek's reply, you may find some examples how to use the RDKit MMFF94 C++ API in Code/ForceField/MMFF/testMMFFForceField.cpp and in Code/ForceField/MMFF/testMMFFHelpers.cpp. All of the constraints are available from C++, a search for "fixed atoms"

Hi Steven, No. 1) is exactly what I'm doing to preform rigid protein minimization of ligands. I use ff.AddFixedPoint() to fix all protein atoms (you could omit the desired side chains). For better performance I also use following params: ff = AllChem.MMFFGetMoleculeForceField(comp, ff_mp,

2016-04-01 Thread Steven Combs
Hi, Is it possible to do a minimization in mmFF in context of two small-molecules or a single small molecule and sidechains from a binding pocket? From what I gather, I have two options: 1) Make a single RWMol object with the ligand and all residues from the binding pocket, then run mmFF on the
