We'd like to announce the OpenMM command - a way for users to run an OpenMM simulation without writing a script. It is analogous to packages such as grompp/mdrun in GROMACS or tleap/pmemd in AMBER.
A few features:
- Sets up your system starting from coordinates and force field.
- Configuration options accessible via command line or configuration file.
- Configuration file is automatically generated for reproducibility.
- Automatic reading and writing of restart files.
- As the program runs, OpenMM scripting commands are printed to screen.
- Real-time reporting of simulation progress, including estimated time remaining and speed in nanoseconds/day.
To run the command, type in something like this:
Code: Select all
[color=#0040FF]./openmm --coords dhfr.pdb --protein amber99sb --water tip3p --cutoff 0.9*nanometer --platform CUDA --n_steps 100000[/color]
Code: Select all
[OpenMM] Number of available platforms: 4
[OpenMM] Selected Platform: CUDA
[OpenMM] CudaDeviceIndex = 0
[OpenMM] CudaDeviceName = GeForce GTX TITAN
[OpenMM] CudaUseBlockingSync = true
[OpenMM] CudaPrecision = mixed
[OpenMM] CudaUseCpuPme = false
[OpenMM] CudaCompiler =
[OpenMM] CudaTempDirectory = /tmp
