This version has the following updates.
- (ATDYN) QM/MM with AMBER force field
- (ATDYN) Interface with QSimulate-QM
This version has the following updates.
- (ATDYN) QM/MM MD
- (ATDYN) Minimum Energy Path Search
- (Analysis) Spatial Decomposition Analysis (SPANA) (sasa, rdf, density, hbond, contact)
Ver. 2.0 beta is quite faster than ver. 1.X, and also optimized for the FUGAKU super-computer. Note that the available functions are currently limited to only SPDYN, since this is a pre-release version. For details, see the “Download” page.
This version has the following updates.
- (ATDYN) Fix L-BFGS minimization
- (SPDYN) Fix free-energy perturbation
- (SPDYN) Enable local restraints in free-energy perturbation
- (Analysis) Fix mbar_analysis
- (Analysis) Stop energy_analysis if there is non-desired mixtures of solvent and solute in angle/dihed/improp/cmap
- (general) extend maximum characters per line in control file (for recent CHARMM-GUI)
This version has the following new features.
- Free-energy perturbation method (FEP)
- On-the-fly energy analysis in gREST
- Isolated system (no-PBC w/ or w/o spherical boundary potential)
Joint tutorial of GENESIS, RedMDStream, and MINT was held on November 20-22 at University of Warsaw in Poland (website). Thank you for your participation!
