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.

It is a commandline tool to manipulate .xyz molecule files.

2DFLT it is first out of two programs which allows implementation of Phase Sensitive Detection (PSD) and/or Modulated Enhanced Diffraction (MED) techniques on the in situ data. This software allows collecting individual data files from in situ experiment into one dataset. After that this data set can be visualized, edited, normalized and averaged. Resulted data can be saved as one flat file (FLT-format) which can be used for PSD/MED calculations via 2DMED software (http://sourceforge.net/projects/twodmed/?source=directory). 2DFLT specifically was written to target in situ X-ray Powder Diffraction data from synchrotron measurements. Hence it can read CHI, XYE (TOPAS), FXYE(GSAS/ GSASII) and XY- files formats. However it can read general in situ data written into individual TXT or XY – files.

2DMED it is the second out of two programs which allows implementation of Phase Sensitive Detection (PSD) and/or Modulated Enhanced Diffraction (MED) techniques on the in situ data. This software takes normalized and averaged in situ data in flat file format (FLT) and performs PSD transformation which has been described in Urakawa, A.et al. Chem. Eng. Science 2008, 63, 4902. User can choose demodulation index k and perform several demodulation calculations. This is extremely important since demodulation calculations at k = 2 on in situ powder diffraction data represent implementation of MED method which been described in Chernyshov, D. et al. Acta Cryst. 2011, A67, 327. Demodulated data can be then viewed on 2D and/or 1D plot and analyses with different tools including In Phase Plot, Maximum Amplitude Plot and Positive Pattern Plot. Demodulated data also can be saved in ASCII format for further analysis.

The Developement of 3D Molecular Simulation Engine

3DMolvis is a tool designed to make easy learning of basic structure and function of biological molecules.

4-Dimensional Cell Simulator (4DiCeS) is a framework on hybrid (stochastic and deterministic) modeling and simulation of (whole) cell environments in 4D. The framework may incorporate any reaction and diffusion algorithms applicable in a 4D grid layout.

Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented in reasonable times with modern computing power. This project makes the source code (and command line Windows executable) developed in that study openly available for scientific and engineering uses.

ABE is a small, fast and convenient program for visualizing and modeling experimental bioassay data. The data can be modeled using either polynomials or a more specific four-parameter model based upon the standard, sigmoidal dose-response curve.

Project for develop force fields with using ab-initio calculations

This project is A Mitochondrial OxydoReduction Simulation System. It consists of two linked projects: a program for displaying and analysing large biomolecular systems (Floral) and a multi-agent simulator for biomolecular oxydoreduction systems (AMORSS).

APBSmem is a Java-based graphical user interface for Poisson-Boltzmann electrostatics calculations at the membrane. APBS version 1.2.0 or later is required.

Monte Carlo simulations of various classes of asymmetric exclusion processes (ASEP) with open and periodic boundaries. ASEP is a paradigmatic model of non equilibrium statistical mechanics. It can be utilized to model various non-equilibrium phenomena in Biology such as molecular motor transport and protein synthesis. The code's comments will be gradually expanded upon; if there are mistaken or unclear comments they will be corrected. We cannot give an estimation as to when because this is a side-project of ours, and the comments are not crucial to the code's workings.

The core of this program is a interactive periodic table of elements but also has a handful of goodies Including: A bohr model generator, a nice mix & match memory game, a nifty find dialog. The periodic table is built for quick lookup of basic info

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.

A framework to support scientific experiments: acquiring, visualizing, analyzing, and managing experimental data. Initially developed to support the experimental process on two beamlines at the Canadian Light Source synchrotron (lightsource.ca).

This is an implementation of the adaptive biasing force method (ABF) in NAMD. The code for ABF was developed by Eric Darve, Stanford University. ABF is a method created by E. Darve and A. Pohorille to calculate the free energy of bio-molecules.

"Information is data in action", and, consequently, having good quality data is essential. The AESTEL package contains two highly configurable applications for data management: A data loader and a reporting application, i.e. DataLoader and AEREA, respectively. The data loader application applies user-defined instructions to validate, process and load data. The reporting application provides a query builder and spreadsheet template designer. Both applications work with any relational data model. (Postgres and Oracle have been tested). The two applications have been initially developed for small molecule drug discovery research. However, they can be extended for use in other data domains.

Alchemy Linux is a Linux distribution (based on Fedora) for chemists (and mathematicians and physicists). This remix comes with a whole set of packages to help with experiments, simulations and publications. (This project is not maintained or endorsed by Red Hat or the Fedora project).
