[gmx-users] Determining a ligands permeability

2017-11-05 Thread Chetan Puri
I have tried to do an umbrella sampling for a ligand (drug) and membrane as per the gromacs tutorial. Now i want to calculate permeability and diffusibility for this ligand, so can anyone suggest how to proceed further. Since there is some literature available but it does not show the proper method
