ChemApp is a programming tool from the area of computational thermochemistry. It is a library consisting of a rich set of subroutines, based on the thermodynamic phase equilibrium calculation module of ChemSage. It permits the calculation of complex, multicomponent, multiphase chemical equilibria and their associated energy balances. ChemApp is available as object code for a wide range of platforms and as a shared library/DLL. ChemApp "light" is the free version of ChemApp, and although it is restricted in two ways compared to the regular version, it gives you almost the same functionality.
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.
