Parameters controlling a NAMD run

Single-valued attributes:

  • single-core: whether or not to run namd on a single core; if false, namd3 will be used if available and appropriate for the system size (default: False)

  • cpu-override: revert to cpu version of namd3 (default: False)

  • vacuum: if true, namd will run on a single node even if multiple nodes are allocated (default: False)

  • ensemble: Name of ensemble to run in; note that NPT can only be performed on a solvated system (default: NVT)

  • minimize: Number of minimization steps; ignored if ensemble is not ‘minimize’ (used with the ‘minimize’ command) (default: 1000)

  • nsteps: Number of MD time steps; ingored if ensemble is ‘minimize’ (used with the ‘run’ command) (default: 2000)

  • dcdfreq: number of time steps between configuration output to DCD file (default: 100)

  • xstfreq: number of time steps between cell size output to DCD file (default: 100)

  • temperature: Temperature (K) for NVT or NPT (default: 300)

  • pressure: Pressure (bar) for NPT; note that NPT can only be performed on a solvated system (default: 1)

  • other_parameters: key:value pairs for other namd2 configuration file statements

  • colvar_specs: colvar specifications; dict with keys ‘groups’, ‘distances’, and ‘harmonics’
