Open Source Cygwin Molecular Science Software

Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science and related areas. It offers a flexible rendering framework and a powerful plugin architecture.

This is a collection of software modifications created to integrate NanoEngineer-1, PACKMOL and MSI2LMP for the purpose of easily creating molecular dynamics cells. NanoEngineer-1 is a molecular CAD software written by Nanorex and provides the user an easy way to create molecules, while the software modifications allow the user to type atoms using multiple force fields. PACKMOL can generate a random collection of molecules using the molecule templates from NanoEngineer-1 thus providing the initial MD cell. Modifications to PACKMOL allow the atom type data to be passed through to the MSI2LMP software. MSI2LMP creates a LAMMPS input file based on class I or class II force fields. MSI2LMP was modified to use numerically coded force field data generated by NanoEngineer-1. The MMP file format was extended and integrated into all three software applications. http://www.nanoengineer-1.net http://www.ime.unicamp.br/~martinez/packmol/ http://lammps.sandia.gov/

NOTE: Project moved to https://github.com/MolBIFFM/PTGLtools. The Visualization of Protein-Ligand Graphs (VPLG) software package computes and visualizes protein graphs. It works on the super-secondary structure level and uses the atom coordinates from PDB files and the SSE assignments of the DSSP algorithm. VPLG is command line software. If you do not like typing commands, try our PTGL web server: http://ptgl.uni-frankfurt.de/

This software has moved to http://www.poissonboltzmann.org/.

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

This application is intended to help students with the basics of chemistry. It can solve basic gas laws equations, and find the molar mass of a compound or element. These tasks allow students to cut the repetition out of basic chemistry.

HOPPscore is a simple application for evaluating the structural quality of theoretical or experimental protein structures. Protein are evaluated by comparing structure fragments to a reference dictionary of fragments from high resolution structures.

Magnetic Drug Targeting (MDT) simulation and visualization in traversal and longtitudinal mode.

Polymer simulation utilites for bead coarse-grained models of polymers. Includes 1) lattice monte carlo. Many kinds of lattices are supported. It shouldn't be a problem to implement any new specific one (discrete models) 2) off-lattice monte carlo and molecular dynamics (continuous models) Latter one is rebuild of earlier version of simpatico (http://gemini.cems.umn.edu/research/morse/code/simpatico/home.php) project. Input and output are based on PDB file format which is better to visualize with pymol. For specific non-pdb input/output of 2nd program there are convertation utils also available. Programs are expected to compile in gcc under cygwin or pure linux environment. Scripts to run many copies of program under pbs/torque cluster system are also available.

News: V2.2 with performance enhancements, bug fixes and new features released on 06/26/2017. Sources are available with binaries to follow soon. News: V2.1 with many improvements released on 07/15/2016. Sources and binaries are available. RMG is a density functional theory (DFT) based electronic structure code that uses real space grids to represent wavefunctions, charge densities and ionic potentials. Designed for scaleability it has been run successfully on systems with thousands of nodes and hundreds of thousands of CPU cores. It is currently under active development and contributions are gladly accepted.
