Object-oriented crystallographic library and program, for the analysis of Crystal structures from scattering experiments: optimized scattering computation, Graphical interface for structures and data, global optimization algorithms.

nmrshiftdb2 is a NMR database (web database) for organic structures and their nuclear magnetic resonance (nmr) spectra. It allows for spectrum prediction (13C, 1H and other nuclei) as well as for searching spectra, structures and other properties. The nmrshiftdb2 software is open source, the data is published under an open content license. The core of nmrshitdb2 are fully assigned spectra with raw data and peak lists (we have pure peak lists as well). ...

AMBIT offers a cheminformatics data management for chemical substances, structures and nanomaterials. Flexible structure, similarity and study queries storage, descriptor calculation and predictive models building via REST web services.User interface for creating read across assessment and generating reports, aligned with regulatory and industrial requirements.

Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other...

The Chemistry Development Kit (CDK) is a scientific, LGPL-ed library for bio- and cheminformatics and computational chemistry written in Java. The main home page of the CDK is now at: http://cdk.github.io

...To address this limitation we created HostDesigner, a code that builds and evaluates millions of molecules in minutes. This command line executable builds 3D molecular structures by covalently connecting user-defined input fragments with pre-computed hydrocarbon fragments from a library. The results are ranked with respect to desired geometric constraints defined by the user. See the User's Manual for further details including a list of literature citations for example applications. Download includes User's Manual, HostDesigner 4.3 source code (in Fortran), data files, example input, HDViewer executables for MacOS, Linux, and Windows, and mengine source code (in C). ...

A collection of cheminformatics and machine-learning software written in C++ and Python. NOTE: the RDKit source code and downloads are now in github: https://github.com/rdkit/rdkit The core algorithms and data structures are written in C++. Wrappers are provided to use the toolkit from either Python or Java. Additionally, the RDKit distribution includes a PostgreSQL-based cartridge that allows molecules to be stored in relational database and retrieved via substructure and similarity searches.

We've moved to https://github.com/tjod/gMol/wiki gMol is an interactive visualization system used to display and manipulate 3-dimensional models of scientific data, such as molecular structures and surfaces. It contains both OpenGL and web browser widgets that enable flexible user interfaces.

Diversity assessments and comparisons of large compound databases require calculating similarities of millions of compounds in an affordable time. ParaSim addresses this challenge by parallelizing the calculations according to the number of computing cores available on a single machine. It is optimized for the throughput of very large numbers of query structures against very large numbers of reference structures. As as special feature, ParaSim allows to store and and to access frequently...

Free Organic Chemistry Analysis and Visualisation Tool; Chemical formula editor, calculation of threedimensional molecular structures, high-quality realtime rendering, ...

NMRShiftDB is an open-source, open-access, open-submission, open-content web database for chemical structures and their nuclear magnetic resonance data.

SDFCherry is a command-line program that searches for textual matches in molecular structure files of SDF format and outputs the structures that match. Optionally adds a data field to the matched structures, e.g., biological activity. Useful for QSAR.

WebBabel is a python web application using OpenBabel to convert files from one format to another. It runs under Windows, Mac or Linux on your desktop, workstation or laptop. It uses the Jmol (or Marvin) viewer to show the structures being converted.

The JChemPaint Applet and Swing Application are Java programs for drawing 2D chemical structures like those found in most chemistry textbooks. It is based on the Chemistry Development Kit (cdk.sf.net). Downloads, tracker, and source code repository can be found on https://jchempaint.github.io

Viewmol is a graphical front end for computational chemistry programs. It is able to graphically aid in the generation of molecular structures for computations and to visualize their results.

BlochLib is an expression template library of generic data structures and algorithms to perform large scale nuclear magnetic resonance classical and quantum mechanical spin simulations, with many I/O capabilities,and integrated numerical routines.
