BioXTAS RAW is a program for analysis of Small-Angle X-ray Scattering (SAXS) data. The software enables: creation of 1D scattering profiles from 2D detector images, standard data operations such as averaging and subtraction, analysis of radius of gyration (Rg) and molecular weight, and advanced analysis using GNOM and DAMMIF as well as electron density reconstructions using DENSS. It also allows easy processing of inline SEC-SAXS data and data deconvolution using the evolving factor analysis (EFA) or the regularized alternating least squares (REGALS) methods. Active source code is now maintained on github: https://github.com/jbhopkins/bioxtasraw To install: Check the instructions available at: http://bioxtas-raw.readthedocs.io/en/latest/install.html and in the Files tab. User guides: RAW guides are available at: http://bioxtas-raw.readthedocs.io/ and in the Files tab. To contact us, see: https://bioxtas-raw.readthedocs.io/en/latest/help.html

GSim - free software tool for visualisation and processing of experimental and simulated nuclear magnetic resonance (NMR) spectra.

An open-source software aimed at high-throughput generation of molecular interaction fields (MIFs)

We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and analyzing molecular simulations, in particular of systems of biological relevance. It focuses on a wide availability of algorithms for (advanced) sampling and is capable of combining Monte Carlo and molecular dynamics in seamless fashion. CAMPARI offers the user a very high level of control over all implemented features. For more information and features, please refer to the project's homepage at http://campari.sourceforge.net/V5

The sources and builds history of FDMNES project (http://neel.cnrs.fr/spip.php?rubrique1007&lang=en ) with parallel sparse solvers moved to github: https://github.com/gudasergey/fdmnes

Although many potential applications exist in chemistry and material science, software to allow the general application of de novo structure-based design methods in supramolecular chemistry was non-existent. To address this limitation we created HostDesigner, a code that builds and evaluates millions of molecules in minutes. This command line executable builds 3D molecular structures by covalently connecting user-defined input fragments with pre-computed hydrocarbon fragments from a library. The results are ranked with respect to desired geometric constraints defined by the user. See the User's Manual for further details including a list of literature citations for example applications. Download includes User's Manual, HostDesigner 4.3 source code (in Fortran), data files, example input, HDViewer executables for MacOS, Linux, and Windows, and mengine source code (in C). HostDesigner was developed and posted by author Dr. Benjamin P Hay
