Description Standard Molecular Dynamics (MD) to calculate Residence Times and Binding affinities.

For the MD (Gromacs) calculation will be looking at running 3 calculations to covering the M3 Muscarinic receptor and 2 Adenosine Receptors. These will contain approximately 15,000 atoms and we will have expected simulation times of several milliseconds.

We are likely to want to run these calculations on GPU’s and we expect them to take 1 or 2 weeks of GPU time dependent on the GPU available.
