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...

Gabedit is a Graphical User Interface for FireFly (PC-Gamess), Gamess-US, Gaussian, Molcas, Molpro, MPQC, NWChem, OpenMopac, Orca, PSI4 and Q-Chem computational chemistry packages.

SMSD is a Java based software library for calculating Maximum Common Subgraph (MCS) between small molecules. This will help us to find similarity/distance between two molecules. MCS is also used for screening drug like compounds by hitting molecules, which share common subgraph (substructure).

..., Windows, Android and others. Finally and simplifying my thoughts, I could say, Variables and Procedures are Energy-Quantum, Objects are Atoms, Applications are Molecules, and so System is the Matter.

This project is a small program using Qt for calculation and visualization of electron charge densities in crystals and molecules. It can create a 2D plane of charge densities or create a 1D representation of the charge densities along a given line, in both cases it can also export the graphical representations to various image formats. The program can import various file formats such as space 3D grids of charge density values, created in a quantum chemistry programs Gaussian, Crystal and VASP...

Chromatin accessibility plays a key role in epigenetic regulation of gene activation and silencing. Open chromatin regions allow regulatory elements such as transcription factors and polymerases to bind for gene expression while closed chromatin regions prevent the activity of transcriptional machinery. Recently, nucleosome occupancy and methylome sequencing (NOMe-seq) has been developed for simultaneously profiling of chromatin accessibility and DNA methylation on single molecules. However...

Gene Studio is a free tool for modelling of DNA manipulation. It will allow to work with vectors, to design primers, to clone molecules and provide user friendly intewrface.

This program uses a combination of HTML5 and javascript to interactively draw and edit 3-dimensional structures of small molecules. While several useful web pages are included that require no modification, library calls are documented and examples provided to show how more advanced web pages can be created. A paper describing this program is available at the Journal of Cheminformatics (http://www.jcheminf.com/content/5/1/46).

TreeLiker is a collection of fast algorithms for working with complex structured data in relational form. The data can, for example, describe large organic molecules such as proteins or groups of individuals such as social networks or predator-prey networks etc. The algorithms included in TreeLiker are unique in that, in principle, they are able to search given sets of relational patterns exhaustively, thus guaranteeing that if some good pattern capturing an important feature of the problem...

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.

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

The Chemical Structures Project is a set of 3D structures of molecules in CML format. Each file contains also some physical properties, which can be access using a web browser or a CML file reader.

Quantum Monte Carlo algorithms expressed in Python. This code calculates electronic properties of atoms and molecules from first principles.

QMcBeaver is an object-oriented program to perform Quantum Monte Carlo calculations on atoms and molecules. It is designed to be easy to modify, allowing new ideas to be quickly implemented.

Mito-MAS-m is a simulator of the mitochondrial inner membrane and the enzymatic complexes embedded in it, implementing a coarse-grained (CG) model of the molecules using rigid structures and Dissipative Particules Dynamics (DPD) as motion equation.

PFMD performs a Molecular Dynamics simulation of some polarizable fluids at the liquid state by means of a dissociable potential. Supported molecules are H2O (water) and MX3, where M is a metal among Al, Fe, or Ga and X is a halogen among Cl, Br, or I.
