relax
Molecular dynamics by NMR data 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. -

Argo
ARGO is a program for analysis of electronic structure calculations
The `Argo' program draws its name from ancient Greek, referencing the vessel of the same name commissioned for Jason's renowned Argonauts expedition. This choice symbolizes the pursuit of making the best use of quantum chemical calculation results. ARGO facilitates the analysis of results obtained from quantum chemistry codes, specifically Gaussian. This task is achieved through a set of Python scripts. Our code is freely available throughout the academic community with the ambition to be used, to be supplemented by others, and become an indispensable tool for optimum utilization of quantum chemical calculation results. -

Jljp
Calculates the voltage across a liquid junction between two solutions
...It's a tool for scientists and engineers who have to do with electrochemistry and electrokinetics. When two solutions containing ions are put into contact, possibly through a porous diaphragm, a voltage develops across them. The calculation of the voltage is not trivial. The program is written in Java. Includes classes that can be included in other programs, together with graphical interfaces (also as an applet). -

CoolingPower
Print Steam Tables; Plot diagrams and cycles from equations of state
CoolingPower is NOT in a condition for use at this time. A couple of bugs have been discovered that severely affect the calculation accuracy. While I troubleshoot, use at your own risk. Once completed, CoolingPower will have the capability to plot diagrams of thermodynamic properties, construct Steam Tables, and plot thermodynamic cycles. Initial fluid will be water/steam, but functionality will extend to include a variety of working fluids. CoolingPower operates in GUI format and, for Unix-based machines, from the terminal. ... -

nwhess2freq
Calculates frequencies/modes from an nwchem generated hessian
...The advantage of having a separate script for this is that you can use the same hessian to calculate frequencies for different isotopic substitutions i.e. you only have to run one nwchem calculation. The script is finished in its current form in the sense that it is feature complete. Feel free to amend, translate, copy, steal etc. See the README in the code repository for instructions. Installation: Simply download the file and start Octave in the download directory. -
