The BioJava Project is an open-source project dedicated to providing Java tools for processing biological data. This will include objects for manipulating sequences, file parsers, CORBA interoperability, access to ACeDB, dynamic programming, and simple statistical routines. The BioJava library is useful for automating those daily and mundane bioinformatics tasks. As the library matures, the BioJava libraries will provide a foundation upon which both free software and commercial packages can be developed.

Free, open source molecular viewer and editor for protein structure, DNA structure, PDB, molecular rendering, biological macromolecule. Atoms may be drawn as spheres of different sizes. Bonds may be drawn as cylindrical sticks, conical sticks or as curved surfaces. Five types of slab are available: planar, spherical, semi-spherical, cylindrical and semi-cylindrical. The slab position and thickness are visible in a small window. Atomic bonds as well as atoms are treated as independent drawable objects. and more.

Fluctuate fits the model which has a single population which has been growing (or shrinking) according to an exponential growth law. It estimates 4Nu and g, where N is the effective population size, u is the neutral mutation rate per site, and g is the growth rate of the population. Fluctuate forms part of the Lamarc (Likelihood Analysis with Metropolis Algorithm using Random Coalescence) suite. See: http://evolution.genetics.washington.edu/lamarc.html

tRNAscan-SE was written in the PERL (version 5.0) script language. Input consists of DNA or RNA sequences in FASTA format. tRNA predictions are output in standard tabular or ACeDB format. tRNAscan-SE does no tRNA detection itself, but instead combines the strengths of three independent tRNA prediction programs by negotiating the flow of information between them, performing a limited amount of post-processing, and outputting the results in one of several formats.

Dinotrace is a signal waveform tracing tool that supports traces in the form of Verilog Value Change Dump (VCD), ASCII, Verilator, Tempest CCLI, COSMOS, Chango and Decsim Binary. Dinotrace is also equipped with an interface to GNU Emacs. Dinotrace was conceived in the early 1980's by Allen Gallotta at Digital Equipment Corporation, who wrote the code and supported it through version 4.2. When created, it was the first graphical display tool for the simulators being designed at Digital.

Electric is a sophisticated electrical CAD system that can handle many forms of circuit design, including: Custom IC layout (ASICs) Schematic drawing Hardware description language specifications Electro-mechanical hybrid layout (snip, this is an edited version of Electric's homepage) Electric handles these file formats: CIF I/O GDS I/O VHDL I/O DXF I/O PostScript, HPGL, and QuickDraw output For real functionality, one should consider installing support simulation software such as cad/spice.

FEAPpv is a general purpose finite element analysis program which is designed for research and educational use. The program is described in the references: The Finite Element Method, 6th ed., Vols. 1 and 2, by O.C. Zienkiewicz and R.L. Taylor, Elsevier, Oxford, 2005. FEAPpv is designed to be compatible for compilation in Unix/Linux and Windows PC environments. No support on use of the program will be provided.

PCB is an interactive printed circuit board editor for the X11 window system. PCB includes a rats nest feature, design rule checking, and can provide industry standard RS-274-X (Gerber), NC drill, and centroid data (X-Y data) output for use in the board fabrication and assembly process. PCB offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time.

Open CASCADE Technology is a software development platform freely available in open source. It includes components for 3D surface and solid modeling, visualization, data exchange and rapid application development. Open CASCADE Technology can be best applied in development of numerical simulation software including CAD/CAM/CAE, AEC and GIS, as well as PDM applications. BUGS: the interesting parts of this port are the libraries, but some components like Wok are not [yet] fully functional.

bg5pdf 是一个用 PDFlib 来把 Big5 编码的文本文件包装成 PDF 文件的简单的包装器。 其输出文件不包含嵌入的字体。你必须下载 Acrobat Acroread Asianfont 包来查看 和打印其输出文件。该包装器除了简单的换行包装外，不提供任何格式化函数。如果你需要 复杂的格式化，你可以试试 CJK-LaText 或者其它类似工具。
