WebThe DCD file format is not well defined. In particular, NAMD and CHARMM use it differently. DCD trajectories produced by CHARMM and NAMD ( >2.5) record time in AKMA units. If other units have been recorded (e.g., ps) then employ the configurable LAMMPS DCD format and set the time unit as an optional argument. The CHARMM program allows for generating and analysing a wide range of molecular simulations. The most basic kinds of simulation are minimizing a given structure and production runs of a molecular dynamics trajectory. More advanced features include free energy perturbation (FEP), quasi-harmonic entropy estimation, correlation analysis and combined quantum, and quantum mechanics - molecular mechanics (QM/MM) methods. francine wiwchar facebook
