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.
XDrawChem is a program for drawing chemical structures. Features include fixed length and fixed angle drawing, a ring tool to automatically draw rings, automatic alignment of structures in reactions, 2D structure diagram generation, and 3D structure conversion. It can access structures in the PubChem compound database by name, CAS number, or formula. It can output InChI for structures and search the database by structure. It can predict 1H NMR, 13C NMR, simple IR spectra, and estimated pKa. XDrawChem can work with its native file format, ChemDraw files, and any format supported by OpenBabel (MDL Molfile, CML, etc.).
Jude is a rapid application development tool to develop data management workgroup applications that easy-to-maintain for developers and easy-to-use for end users. It is based on a knowledge base with an object oriented structure on the server side and a compound document agent-based user interface on the client side.
FlipDCD is a small utility for reversing the endianism of binary DCD trajectory files from Charmm and NAMD. This can be useful when running simulations on one architecture and visualizing or analyzing the results on another. FixDCD is a tiny utility to modify the header of an X-PLOR DCD file to make it readable by programs expecting Charmm DCD files, at the expense of a Timestep size value in the header.
MatDCD is a Matlab package for reading/writing DCD-formatted molecular dynamics trajectory files. It supports Charmm and xplor-format DCD files, it can read both big- and little-endian storage formats, and it can specify which atom indices to load without having to load the entire file.
