DIANNA (Diffraction Analysis of Nanopowders) is a free software developed to simulate atomic models of structures from an ensemble of nanoparticles and to calculate their whole X-ray powder diffraction patterns and the radial distribution function. The main objects of investigation are the particles whose coherent scattering domains do not exceed several nm. DIANNA is based on the ab initio method using the Debye scattering equation. This method makes it possible to obtain information on the atomic structure, shape and size of nanoparticles. It can be applied also to non-periodic materials or coherently ordered structures. How to use: 1. Unzip the archive. 2. Run the "Dianna_Startup.exe" file. 3. Use "Help" through the menu. Required: • Windows 7 or newer • Microsoft .NET Framework 4: www.microsoft.com/en-US/download/details.aspx?id=17851 (Web Installer, 1 Mb) www.microsoft.com/en-us/download/details.aspx?id=17718 (Standalone Installer, 48 Mb) • Microsoft Visual C+

The Sashimi project hosts the Trans-Proteomic Pipeline (TPP), a mature suite of tools for mass-spec (MS, MS/MS) based proteomics: statistical validation, quantitation, visualization, and converters from raw MS data to the open mzML/mzXML formats.

MESMER is designed to analyze and simulate reactions in the gas phase that take place on a potential energy surface that is characterized by having one or more potential wells, and which are typically described by rate coefficients that depend on pressure (or concentration) as well as temperature. MESMER allows you to simulate systems over a wide range of pressures and temperatures, extract rate coefficients, analyze experimental data, fit model parameters and represent rate coefficients in formats that can be used directly in large scale simulations (e.g. Cantera or Chemkin).

RasTop is a molecular graphics program intended for the visualisation of proteins, nucleic acids and small molecules based on the popular Rasmol software. The program is aimed at the rapid visualization and analysis of molecules.

Molsketch is a 2D molecular editing tool. Its goal is to help you draw molecules quick and easily. Of course you're creation can be exported afterwards in high quality in a number of vector and bitmap formats.

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).
