The OpenMM team has reviewed the links on this page, but we encourage the community to add their own.
Omnia An open source ecosystem built around OpenMM.
OpenMMTools Integrators, enhanced sampling methods, test systems, and alchemical factories for OpenMM.
OpenMM Setup A graphical application to set up and run simulations with OpenMM. Includes pull-down menus, pop-up tips, error checking, and live script building capabilities.
PME Optimizer A script to optimize the performance of PME. It runs a series of simulations and selects the parameters that give best performance for simulating a particular system on particular hardware.
OpenMM-MD A general purpose script (with lots of comments) that uses the OpenMM Python module to drive MD simulations. Simulation options are handled via an input file. To facilitate use of the script, the available options are always printed out for you to see, along with documentation.
