PySCeS is the Python Simulator of Cellular Systems. For a network of coupled reactions it does a stoichiometric matrix analysis, calculates the time course and steady state, and does a complete control analysis.

The software package 'relax' is designed for the study of molecular dynamics through the analysis of experimental NMR data. Organic molecules, proteins, RNA, DNA, sugars, and other biomolecules are all supported. It supports exponential curve fitting for the calculation of the R1 and R2 relaxation rates, calculation of the NOE, reduced spectral density mapping, the Lipari and Szabo model-free analysis, study of domain motions via the N-state model and frame order dynamics theories using anisotropic NMR parameters such as RDCs and PCSs, the investigation of stereochemistry in dynamic ensembles, and the analysis of relaxation dispersion data.

Steam tables for industrial use according to the international standard for the properties of water and steam, the IAPWS-IF97 formulation and the international standards for transport and other properties. Hummeling Engineering BV develops engineering software in the fields of thermodynamics, mechanics, hydrodynamics, and digital signal processing.

VASPMO aims at visualizing wavefunctions (or molecular orbitals) from VASP calculations. It reads VASP's output files PROCAR and CONTCAR, and exports an *.out file in Gaussian's output format, which can be visualized by many popular visualization tools, such as JMol, Molekel, Chemcraft, Gabedit and Molden, etc. These tools can further generate *.cube files, which can be visualized by an even wider range of softwares. 读入VASP计算得到的PROCAR和CONTCAR文件，输出Gaussian结果文件。该文件能够被常用的量子化学可视化软件（如Molekel、Chemcraft、Gabedit、Molden和JMol等）读取，进而绘制和观看体系的分子轨道。有些软件还能导出 cube文件（如Chemcraft和Molden等），从而又能被很多支持cube格式文件的可视化软件所识别。

MatNMR is a highly flexible toolbox for processing 1D and 2D NMR/EPR spectra in MATLAB and creating high-quality 1D, 2D or 3D plots. Fully GUI and/or script-based.

GVIB is a user friendly package for vibrational analysis. Given a molecular geometry, it will calculate vibrational frequencies and intensities using anharmonic internuclear potential.

OpenGrowth is a research program which grows new ligands in proteins by connecting small organic fragments. The details can be found in the original publication "OpenGrowth: an automated and rational algorithm for finding new protein ligands" (J. Med. Chem., http://dx.doi.org/10.1021/acs.jmedchem.5b00886). To use OpenGrowth, you will need OpenGrowth_1.0.zip and Resources_1.0.2.zip that can be found by clicking on the Files menu in the horizontal bar at the top (https://sourceforge.net/projects/opengrowth/files). OpenGrowthGUI, FOG2.0, and the 3Mer-Screen stand-alone can be found in OpenGrowth_1.0.zip. To prepare new fragments you need BuildingFragments_1.0.1.zip and the scripts for MD simulations are in MD-Scripts_1.0.1.zip. SMoG2016.tar.gz allows to compute a score with the newly developed function (J. Chem. Inf. Mod., http://pubs.acs.org/doi/abs/10.1021/acs.jcim.6b00610). For any questions, please send emails exclusively at opengrowth-discuss@lists.sourceforge.net.

This application will show you the periodic table and it also has a huge amount of data for each element in the periodic table. Almost every term for the element is described!

QMcBeaver is an object-oriented program to perform Quantum Monte Carlo calculations on atoms and molecules. It is designed to be easy to modify, allowing new ideas to be quickly implemented.

Bmrblib is a Python API abstracting the Biological Magnetic Resonance Data Bank (BioMagResBank or BMRB) NMR-STAR format (http://www.bmrb.wisc.edu/). It allows the writing of NMR-STAR files for BMRB data deposition and the reading and easy extraction of data from files residing in the BMRB data bank, all without knowledge of the Self-Defining Text Archive and Retrieval (STAR) format.
