Open source steam property routines in C. Implements the IAPWS-IF97 steam tables from the International Association for the Properties of Water and Steam. Includes two-way property solvers and test suite. Can be used from C/C++, Fortran, Python, LabVIEW, Octave and ASCEND.

Diversity assessments and comparisons of large compound databases require calculating similarities of millions of compounds in an affordable time. ParaSim addresses this challenge by parallelizing the calculations according to the number of computing cores available on a single machine. It is optimized for the throughput of very large numbers of query structures against very large numbers of reference structures. As as special feature, ParaSim allows to store and and to access frequently queried datasets as persistant objects in memory for short response times. ParaSim calculates chemical similarities based on binary structural fingerprints. It does not compute fingerprints by itself but relies on third party software to do so. Basically, all types of structural fingerprints which can be stored in an array of bits (a bitset) can be used by ParaSim. See the Wiki (https://sourceforge.net/p/parasim/wiki/Documentation/) for detailed documentation. FEEDBACK HIGHLY APPRECIATED!

Vibeplot presents a new and attractive way to visualize vibrational analysis from density functional calculations (DFT). It is especially targeted at the chemists. The interface can either be scripted or used interactively with QVibeplot.

IFEFFIT is a library and set of interactive programs for the analysis of x-ray absorption fine-structure (XAFS) data. IFEFFIT combines state-of-the-art analysis algorithms with graphical display of XAFS data, and general data manipulation. It can be

PAScual is a data analysis suite for Positron Annihilation Lifetime Spectroscopy (PALS).

RASP uses structure-based chemical shift predictions to solve the backbone resonance assignment problem in protein NMR spectroscopy. This enables rapid determination of highly accurate assignments on the basis of minimal experimental datasets, even for spectroscopically challenging proteins. RASP takes as input spin systems assembled on the basis of an arbitrary set of conventional triple-resonance NMR experiments. Uniquely, RASP is capable of extensive assignments even in the abscence of Cbeta chemical shift information: over a test set of 154 proteins RASP assigns 88 % of residues with an accuracy of 99.7 %, using only information available from HNCO and HNCA spectra. RASP is described here: MacRaild and Norton (2014) RASP: Rapid and robust backbone chemical shift assignments from protein structure. J Biomol NMR doi:10.1007/s10858-014-9813-7

Metmask has moved to github http://github.com/hredestig/metmask Metmask is a tool written in python for managing chemical identifiers for metabolomics experiments. It can incorporate identifiers from local textfiles, several online databases, query PubChem and record all found associations in a local sqlite database.

This python package aims to help people set up and analyze molecular dynamics simulations in aqueous-organic solvent mixtures. See D. Alvarez-Garcia et al. Journal of Medicinal Chemistry, 2014.

An isotopic pattern calculator written in Python 3. Given a chemical formula, it calculates the full isotopic distribution and simulates a mass spectrum. Dependencies: Python 3.6+, numpy, matplotlib, tkinter. The old python 2.x code has been updated and given a GUI. It's also a lot faster now.

The Acids and Bases chapters' (14 and 15) calculations are arguably the hardest calculations in all of AP Chemistry. With some problems taking as long as ten minutes to solve, the can be hard to wrap the mind around. However, with the Acids and Bases Program, a quick answer is never more than a click away.

BETR-Research (BETRS) is a modelling framework to create spatially resolved multimedia models for the environmental fate- and transport of chemical contaminants. It is intended to serve the research community and can be used as a teaching tool.

This is a .exe program (originally python) to balance chemical equations. Just enter the reactants and the products, and this tool will automatically add the coefficients.

ED Software project contains several programs used (mostly) for processing gas-phase electron diffraction (GED) experimental data.

FABS is a program designed to run a fluorescence/absorption spectrometer on Windows. The program analyzes spectra and provides graphs and data files. Users may choose to input video files from cell phones or other cameras, still images, or even live streams of video from webcams. FABS can perform any necessary calibration and image preprocessing. Experienced users have a number of more advanced options such as background subtraction, adjustments for nonlinearities in detector response, and graph smoothing. FABS was designed with students in mind, as a way to help high schoolers and undergraduates learn about spectroscopy without paying for expensive equipment and software. Accompanying this software is a hardware design, which can be used as a bare-bones spectrometer that will provide quantitative absorption and fluorescence emission spectra at an extremely low cost. It uses only materials that many people can find around their home.

FAUNUS is an object oriented class library for molecular simulation, written in C++. It contains routines and utility programs for, Metropolis Monte Carlo sampling (NVT, NPT, NmuT ensembles), Macromolecules, Proton Titration, Widom Analysis etc.

The GNNPCSAFT Web App is an implementation of our project that focuses on using Graph Neural Networks (GNN) to estimate the pure-component parameters of the Equation of State PC-SAFT. We developed this app so the scientific community can access the model's results easily. In this app, the estimated pure-component parameters can be used to calculate thermodynamic properties and compare them with experimental data from the ThermoML Archive. - CPU-compatible desktop build The standard desktop release requires AVX2. For older CPUs, the runtime-compatible variant can be found with the suffix "-rtcompat-".

Larch is a scientific data processing language that is designed to be easy to use for novices and complete enough for advanced data processing and analysis. Larch provides a wide range of functionality for dealing with arrays of scientific data, and basic tools to make it easy to use and organize complex data. Larch has been primarily developed for dealing with x-ray spectroscopic and scattering data, especially the kind of data collected at modern synchrotrons and x-ray sources. Larch is written in Python and relies heavily on the standard tools for scientific computing with Python (numpy, scipy, matplotlib, and h5py).

Molecular Interaction Potential Generator MIPGEN is a python program that will calculate Molecular Interaction Potential grids over a given molecule, that could be either a protein or a small organic compound (drug). The output will be a series of grids with DX format (*.dx) that the user will be able to visualize using any Molecular visualization program like VMD, PyMol, Chimera... For more information on dependencies and usage, please read the Documentation. Users are welcome to post any bug or request under BUGS & REQUESTS menu. (sourceforge account will be needed).
