OpenMM needs to know where to find these files, so the References to force field definition files that are installed with the GromacsĪpplication. Which stores all the force field parameters directly in a prmtop file, Gromacs just stores Second, we specify includeDir=’/usr/local/gromacs/share/gromacs/top’. For implicit solvent simulations, it usually can be omitted. You only need to do this if you are simulating a periodic Object, we therefore need to tell it the periodic box vectors that were loadedįrom the gro file. Unlike OpenMM andĪMBER, which can store periodic unit cell information with the topology, Gromacs PeriodicBoxVectors=gro.getPeriodicBoxVectors(). Note that when we create the GromacsTopFile, we specify values for two extra This script is nearly identical to the previous one, just replacingĪmberInpcrdFile and AmberPrmtopFile with GromacsGroFile and GromacsTopFile. The units system will be described in more detail later, in Section 12.3.4. We could have equivalently specifiedġ0*angstrom instead of 1*nanometer and achieved the same result. This is an example of the powerful units tracking and automatic conversion facilityīuilt into the OpenMM Python API that makes specifying unit-bearing quantitiesĬonvenient and less error-prone. Note the way we specified the cutoff distance 1 nm using 1*nanometer: Of all bonds that involve a hydrogen atom ( constraints=HBonds). Interactions ( nonbondedCutoff=1*nanometer), and constrain the length ( nonbondedMethod=PME), use a 1 nm cutoff for the direct space Use particle mesh Ewald for the long range electrostatic interactions

System.) It specifies some additional options about how to do that: It creates a System object, which we assign to the variable (More precisely, we invoke the ForceField object’s createSystem()įunction.

The entire OpenMM application programming interface (API), as well as the full Gives you enormous power and flexibility. On the other hand, if you don’t mind doing a little programming, this approach So you never need to type a single line of code! There is even a graphical interface that can write the script for youīased on a simple set of options (see Section 4.5), But it is no harder to write than thoseįor most other applications, and this guide will teach you everything you need “script” that specifies the details of the simulation to run. Nearly all molecular simulation applications ask you to write some sort of To know anything about Python programming (or programming at all) to use it. Those libraries can easily be chained together toĬreate Python programs that run simulations.
Rather, it is a collection of libraries written in the Not exactly an application in the traditional sense: there is no program called The first thing to understand about the OpenMM “application layer” is that it is The OpenMM Application Layer: Introduction ¶
