Scaffold Hunter is a JAVA-based software tool for the analysis of structure-related biochemical data. It enables generation of and navigation in a scaffold tree hierarchy annotated with various data.

Effectopedia is open knowledge aggregation and collaboration tool that provides a means of describing adverse outcome pathways in encyclopedic manner.

JOELib/JOELib2 is a cheminformatics library which supports SMARTS substructure search, descriptor calculation, processing/filtering pipes, conversion of file formats, 100% pure Java, and interfaces to external programs (e.g. Ghemical) are available.

PyVib2 is a program for analyzing vibrational motion and vibrational spectra. It is an open source "all-in-one" solution for scientists working in the field of vibrational spectroscopy (Raman and IR) and vibrational optical activity (ROA and VCD).

Structure is a framework for two-dimensional molecular visualization written in Java and based on Octet.

The CCP1GUI project aims to develop a free, extensible Graphical User Interface to various computational chemistry codes developed by the worldwide academic community, with an emphasis on ab initio Quantum Chemistry codes.

Vibeplot presents a new and attractive way to visualize vibrational analysis from density functional calculations (DFT). It is especially targeted at the chemists. The interface can either be scripted or used interactively with QVibeplot.

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.

Sharing lists of molecular structures with associated chemical properties is a common task in computer-aided drug design and medicinal chemistry. WebChem Viewer is a simple, free, open-source program that generates HTML-formatted output that can be viewed in any modern web browser, on any operating system (including mobile), without requiring the installation of additional software. The output can also be easily incorporated into existing web pages. WebChem Viewer is released under the FreeBSD license. It was created by Jacob Durrant, a post-doc in the lab of Rommie E. Amaro.

--UPDATE-- New Version is now integrated in the official PyMOL plugin repository! --UPDATE-- The BNI (Beyond Normal Interaction)- Tools is a plug in for the PyMOL molecular visualization system which adds additional functionalities and presets to the PyMOL GUI and also adds useful extended commands.

4-Dimensional Cell Simulator (4DiCeS) is a framework on hybrid (stochastic and deterministic) modeling and simulation of (whole) cell environments in 4D. The framework may incorporate any reaction and diffusion algorithms applicable in a 4D grid layout.

Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented in reasonable times with modern computing power. This project makes the source code (and command line Windows executable) developed in that study openly available for scientific and engineering uses.

"Information is data in action", and, consequently, having good quality data is essential. The AESTEL package contains two highly configurable applications for data management: A data loader and a reporting application, i.e. DataLoader and AEREA, respectively. The data loader application applies user-defined instructions to validate, process and load data. The reporting application provides a query builder and spreadsheet template designer. Both applications work with any relational data model. (Postgres and Oracle have been tested). The two applications have been initially developed for small molecule drug discovery research. However, they can be extended for use in other data domains.

.Net based tools for AnIML formatted data files

Animp is an OpenGL program to display movies of particles in motion where the movies are produced by adding calls to animp library routines to simulation code written in either C++ or Fortran. Animp can also display molecules read from PDB files.

BINViz(Bidirectional Interactive Network Visualization) is a JavaScript library for network and graph visualization. The goal of this tool is to provide a better way to visualize complex graphical models and the underlying data in a web-based environ

Basic life is an application that desires to simulate basic life based on some basic chemistry/physics rules. This environment provides particles that can bond, vibrate, react, etc. in order to create basic cells

Workbench for visualizing biological networks (regulatory, interaction, and metabolic). Can be used as a front-end for BNDB datawarehouses, but also as stand-alone tool.

Brabosphere is a multiplatform application with two main uses: a 3D molecular visualisation tool and a graphical frontend for the quantum chemical program BRABO.

Burrow-owl is a software package for visualizing multidimensional nuclear magnetic resonance (NMR) spectra, with an emphasis on spectra used in macromolecular structure determination.

COMSPARI (COMparison of SPectral And Retention Information) is being developed to 1) visualize mass spectrometric data and, more importantly, to 2) visualize 2 sets of mass spectral data simultaneously in a format that easily allows for comparison.

Canvas-2DGC is a user-extensible, Freemat based 1DGC and comprehensive 2DGC (GCxGC) data visualization and processing software. GCxGC-MS data analysis is supported for Agilent GCMS data format. The first goal of this project is to provide a highly intelligent analytical tool for reducing a complex chromatographic data analysis, either 1D or 2D, to just a few simple and intuitive steps. The second goal is to provide a fast and practical way of customizing or extending functionalities by ordinary users through high-level Freemat scripting. Freemat, one of open source Matlab clones, is chosen for this very purpose, because its syntax is most compatible with Matlab and it is lightweight - very suited for ordinary users.
