The Open Chemistry project develops a suite of open-source applications and libraries, such as Avogadro and Chemkit, to enhance workflows in computational chemistry and related fields. These applications facilitate data integration, visualization, and analysis for chemical structures and simulations, leveraging high-performance computing resources. The project emphasizes the use of open data, standards, and source code to foster collaboration and innovation in scientific computing.

Avogadro Open Chemistry Chemical Data Explorer The Avogadro project is a cross-platform, open-source approach to building chemical The Open Chemistry project is developing a suite of applications and support libraries The Chemical Data Explorer is an cross-platform, open-source application that structures. It uses external simulation packages in addition to integrated analysis and to improve the workflow in computational chemistry, biology, materials science and builds on the capabilities of the Visualization Toolkit, Qt and MongoDB. It can visualization routines. The work presented here illustrates a workflow for quantum related areas. A set of open, connected components that can tackle small problems connect to a local or remote database, ingest new data from various sources and mechanical calculations, allowing the preparation of chemical structures, rough on the desktop, and big research projects requiring significant time on the world’s top make that data semantically rich. It can apply informatics techniques to the data optimization, and subsequent calculation of electron density isosurfaces, molecular supercomputers. it contains to search for structures with particular properties. Work is ongoing to orbitals, etc. more tightly integrate computational job storage and search.

OpenQube Avogadro allows the user to prepare jobs for quantum packages, such as NWChem, OpenQube is a small, open-source C++ library that reads key quantum data from Figure 3: The user interface showing a query and structures (top-left), a scatter plot matrix (top-right), scatter GAMESS, Gaussian and Q-Chem. Due to the plugin-based nature of the Avogadro calculations produced by codes such as NWChem, GAMESS and Gaussian. It can plot with tooltip (bottom-left), and K-means clustering (bottom-right). project, many specialized functions can be added for a large range of applications, read in basis sets, eigenvectors and density matrices, and calculate the magnitude such as molecular docking, surface modeling and electronic structure. of the molecular orbitals and electron density on regularly-spaced grids. The data produced can be used for further analysis and visualization of electronic structure. Visualization Toolkit and ParaView The Visualization Toolkit (VTK) is an open-source, C++ toolkit for 2D and MoleQueue Chemkit 3D graphics, volume rendering, image processing, visualization and modeling. The MoleQueue application provides a graphical interface that integrates high- Development began in 1993, and it now has a large community of developers Chemkit is an open-source, C++ library for molecular modeling, cheminformatics, performance computing (HPC) resources on the desktop. It offers a seamless distributed around the world in a diverse set of fields. VTK processes data using and molecular visualization. It features a modular, plugin-based architecture and integration layer for applications, such as Avogadro, to submit jobs to local and a data flow graph (pipeline) in which each algorithm takes zero or more inputs includes over 40 plugins that implement 15 file formats, 6 line formats, 4 force-fields, remote computational resources. Job lifetime is managed by MoleQueue, and results and produces zero or more outputs. VTK is scalable to large data because it has 2 partial charge models, 2 aromaticity models, 8 atom typers and 30 molecular can be opened in any external program. distributed algorithms that use MPI to execute on large computing clusters. descriptors. In addition, Chemkit includes an integrated visualization library built on OpenGL/Qt, with Python bindings for easy scripting.
