An application for first-principles calculation by the joint-DFT method based on a plane-wave basis. By implementation of the joint-DFT method, this application realizes a good convergence for electronic state calculation of molecules in liquid, particular for charged systems. This application is written by C++11, and supports GPU calculation by CUDA. This application also supports diffusive Monte Carlo simulation in cooperation with CASINO.
An open-source application of semi-empirical/ab-initio quantum chemical calculation that comes under an academic license. It performs various quantum chemical calculations based on Hartree-Fock theory, density functional theory, and configuration interaction theory, yielding electronic states and enabling structure optimization and molecular spectrum analysis. Molecular dynamics calculation based on the QM/MM method is also possible by using this software in combination with GROMACS.
ERmod is software for calculating the free energy in soft, molecular aggregate. This program rapidly and accurately calculates the free energy of binding of a molecule in the aggregate through combination of the molecular dynamics simulation and the energy-representation theory of solvation. The solubility of a molecule can be determined with ERmod in arbitrary solvent including supercritical fluid and ionic liquid. Assessment is also possible for the binding strength and site of a molecule in micelle, lipid membrane or protein.
An official Gaussian-series payware for molecular visualization. Must be used with Gaussian, the well-known software of quantum chemistry calculation. This application provides many functions such as molecular modeling, parameter setting, job management and visualization of calculation results. It also performs input file generation for Gaussian, and supports read/write of files with other formats such as Sybyl, Molden, PDB and CIF.
Open Chemistry database that has been in operation since 2004 under the National Institutes of Health (NIH) in the United States. It mainly targets data for small molecules, but information on large molecules such as lipids and peptides are also collected. The database can be accessed via web browser or PUG REST API. The data can be also downloaded from an FTP site.
An application for molecular science simulation. This application covers not only traditional simulation methods implemented in existing applications but also a number of novel methods for quantum chemical calculation. It can perform ab-initio electronic state calculation for a few thousands atoms/molecules as well as trace calculation of transition states in chemical reaction for a few hundreds atoms/molecules. It can also perform high-efficient massively parallel computing on large-scale parallel computers such as the K-computer.
An application program for lattice dynamics calculation of molecules, surfaces, and solids in various boundary conditions. It lays emphasis on analytic calculation of lattice dynamics while it can perform molecular dynamics simulation as well. It supports various force fields to treat ionic materials, organic materials, and metals. It also implements analytic derivatives of the second and third order for many force fields.
An open-source application for atomic structure analysis from powder diffraction data. This application can calculate atomic coordinates, valence sums, and chemical bonds from diffraction data of crystals, nanostructures, and amorphous materials. It is written in Python, and realizes multi-functional fitting and flexible data analysis.
An open-source application for pre- and post-processing for quantum chemistry calculation. This application can handle outputs from Gaussian, GAMESS, and MOPAC as well as the result of other applications via the Molden format. It supports many graphical interfaces such as Postscript, XWindows, VRML, and OpenGL, and performs visualization of molecular orbitals and electron density. It also produces animation videos of molecular vibration.
Software package that implements Behler-Parinello type neural network potential. The package provides tools for training and evaluating potentials based on given structure-energy data. It also provides an interface with LAMMPS for performing molecular dynamics calculations.
