GENESIS Functions
Functions of GENESIS
The GENESIS package contains two MD programs (atdyn
and spdyn
), trajectory
analysis programs, and other useful tools.
- CHARMM force field, AMBER force field, MARTINI model, Go models (Cα Go, all-atom Go, KB Go, and AICG2+), and residue-level coarse-grained DNA/RNA models
- Energy minimization and molecular dynamics simulations
- Leapfrog, velocity Verlet, and RESPA integrators
- SHAKE/RATTLE, SETTLE, and LINCS algorithms for bond constraint
- Bussi, Langevin, and Berendsen thermostat/barostat in the NVT, NPT, NPAT, and NPγT ensembles
- Replica-exchange molecular dynamics method (REMD) in temperature, pressure, and surface-tension space
- Generalized replica-exchange with solute tempering (gREST)
- Replica-exchange umbrella sampling (REUS) with collective variables
- Multi-dimensional REMD method (T-REMD/P-REMD, T-REMD/REUS, gREST/REUS, etc)
- Gaussian accelerated molecular dynamics method (GaMD, GaREUS)
- String method for reaction pathway search
- Hybrid QM/MM (quantum mechanics/molecular mechanics) calculation
- Implicit solvent model (Generalized Born/Solvent Accessible Surface Area model)
- Cryo-EM flexible fitting using all-atom, CG, and implicit solvent models with MD, REMD, and REUS
- Free-energy perturbation method (FEP)
- Anharmonic vibrational analysis using SINDO
- Steered MD and Targeted MD simulations
- Restrained MD simulations (Distance, angle, dihedral angle, position, etc)
- Hybrid MPI+OpenMP, hybrid CPU+GPGPU, mixed double+single precision calculations
- Highly-parallelized Particle mesh Ewald method (PME)
- Scalable MD simulations for huge systems (> 100,000,000 atoms)
- Trajectory analysis tools (RMSD, RMSF, PCA, WHAM, MBAR, etc.)
- Spatial decomposition analysis (SPANA)
MD trajectories obtained by GENESIS can be visualized with VMD and other software. CHARMM-GUI input generator can be used for the preparation of GENESIS input files.
