BioJava aims to provide a comprehensive set of Java components for the rapid development of applications in Bioinformatics. It contains interfaces for representing Sequences, Features, and other important bioinformatics concepts. It can also read and write sequence data in a variety of common formats and communicate with Ensembl databases and with DAS and BioCorba servers.
Jmol is a Free, Open Source molecule viewer and editor. It is a collaboratively developed visualization and measurement tool for chemical scientists. Jmol is an active project, and there are new features being added to it on a daily basis. Users are encouraged to modify it to fit their needs and to contribute their changes to the project.
dnacgr is a program to visualise patterns in DNA and RNA by using Chaos Game representation. It shows the probability of bases and sequences, and can read .fasta and .seq format files. dnacgr can be used for genome analysis, and it reads millions of bases from files in seconds. It runs on the console, and requires SVGAlib. It prints to a file in PNG format.
The Chemistry Development Kit (CDK) is a library of Java classes for chemo-, bioinformatics, computational chemistry, and chemometrics. It provides important algorithms like substructure search, SMILES, Gasteiger charges, QSAR descriptor calculation, 3D structure generation, 2D layout and rendering, many IO formats, atom typing, and more.
Taverna is a collection of workflow enactment and description components, including a high level language for workflows called Scufl (Simple Conceptual Unified Flow Language), a pure Java object model, parser to populate the model, and a set of views and controllers (including some Swing components to drop into your workflow-enabled applications). In order to actually run workflows you also need the myGrid workflow enactment engine.
GeneX Va is a gene expression database supporting storage and analysis of Affymetrix GeneChip technology. It is designed to serve as a secure repository and archive for many researchers' data. It is typically expected to be installed as part of a microarray center; the software is compact enough to install for a single department or even a single user. It includes an Analysis Tree package which includes an ever-expanding set of analytical tools, and has plug-in architecture allowing easy expansion. The "Va" in the name stands for the University of Virginia version, which is a total rewrite of what was originally NCGR's GeneX.
ProActive is a Java library for parallel, distributed, and concurrent computing as well as mobility and security in a uniform framework. It provides a comprehensive API and a graphical interface and is based on an Active Object pattern, a uniform way to encapsulate a remotely accessible object, a thread as an asynchronous activity, an actor with its own script, a server of incoming requests, a mobile and secure agent, and a component with server and client interfaces. It simplifies the programming of applications distributed over a LAN, clusters, an intranet, or Internet GRIDs.
