  AISMIG - An Interactive Server-side Molecule Image Generator:
AISMIG - An Interactive Server-side Molecule Image Generator
AISMIG is a free web-service that enables molecule visualizion without any additional software
like Java or Plug-ins next to a web-browser. You can generate high quality and high resolution
images. It is nice alternative to the standart web-based visualizations techniques because
the user can see and interact with the structure in any case, independend of the software installed
locally. AISMIG is based on PyMol and PovRay.

  AutoDock: Automated docking of flexible ligands to macromolecules:
Designed to predict how small molecules, such as substrates or drug candidates, bind to a receptor of known 3D structure. The atomic affinity grids can be visualised. This can help, for example, to guide organic synthetic chemists design better binders. Free to academics and educational institutions for non-commercial use. For unix or linux; comes with C++ source code included.  

  BALLView:
BALLView is an extensible tool for visualizing and modeling bio-molecular structures. It provides a variety of different models for molecular visualization, e.g. ball-and-stick models, molecular surfaces, or ribbon models.

In contrast to most existing visualization tools, BALLView also offers rich functionality for molecular modeling and simulation, including molecular mechanics methods (AMBER and CHARMM force fields), continuum electrostatics methods employing a Finite-Difference Poisson Boltzmann solver, and secondary structure calculation. Results of these computations can be exported as publication quality images or as movies. Even unexperienced users have direct access to this functionality through an intuitive graphical user interface, which makes BALLView particularly useful for teaching.

For more advanced users, BALLView is extensible in different ways. Owing to its framework design, extension on the level of C++ code is very convenient. In addition, an interface to the scripting language Python allows the interactive rapid prototyping of new methods.

BALLView is portable and runs on all major platforms (Windows, MacOS X, Linux, most Unix flavors). It is open source software and available free of charge under the GNU Public License (GPL) from our website.

  BioEditor:
Once a macromolecular structure has been determined, the challenge is to communicate that information to a widely diverse audience of scientists, educators and students. Current options include the printed literature and dissemination over the Internet, either via online journals or directly on personal web pages. Printed literature has the advantage of wide acceptance and availability, but presents static images. Web pages can be powerful, but lack a uniform format. Furthermore, any dynamic images that are presented are subject to the whims of the providers of the browsers and plug-ins that are required to view them. At the University of California, San Diego and the Scripps Institute, we are developing the BioEditor as a tool to bridge the gap between the printed literature and current Internet presentation formats. It is a standalone Windows application that can be used to prepare and present structure annotations containing formatted text, graphics, sequence data, and interactive molecular views. BioEditor includes a built-in browser based on Internet Explorer; molecular visualizations are done using the Chime plug-in. The executable includes a help file that has a quick-start tutorial to explain how to use all the components of the software. The web site (http://bioeditor.sdsc.edu) includes a download site and some sample documentaries that you can view to see the potential of BioEditor.  

  Calculator Plugins:



Calculator Plugins are modules of Marvin and JChem applications which perform calculations based on chemical structures.

  Chemical and Safety Relational Database:
The software for this resource is open source and is availble for download. A web server outfitted with php and mysql is required to setup your own relational database. The software is OS independent.

This site provides access to a chemical and safety relational database developed in 2003 at Nebraska Wesleyan University. The site is designed specifically for local users but access to the database content is not restricted. This database has many features similar to chemfinder.com and the NIST webbook. The major difference is that the content of the database is determined by local interests and needs and is cross indexed to hazard information (specifically NFPA ratings). For example the database presently contains chemical and safety data for materials used in lab experiments in our first and second year chemistry courses.

The database can be searched by CAS numbers, molecular formula, chemical names, or by specific (NFPA) hazards. Included in the database are files of Chime-pdb files [Chime plugin required for viewing], MSDS's, NFPA ratings (graphic view), and 2D graphics of the molecules. In addition local users can cross-index an unlimited number of web-links to other material (such as IR, NMR, UV-vis and MS spectra, experimental data, potential maps, animations, etc) to each molecule in the database.

  Excel Macros for PDB Files:
Excel spreadsheet macros for reading PDB files, manipulating them, and exporting the modified data in PDB format. These "Renumbering Macros" take a number of PDB-Files in a directory (no more than 250, since the size of an EXCEL workbook is limited to 255 worksheets), read the ATOM and HETATM records of each file into an EXCEL worksheet, and extract the sequences, chain and residue labels into separate worksheets. The user can then process (gap) the sequence alignment manually or export it to gap it automatically with programs such as the GCG module PILEUP and reimport the sequence alignment into the EXCEL workbook. Further macros will then change the chain and residue labels of the PDB files according to a common numbering scheme indicated in the header row (for sequence alignments shorter than 250 amino acids) or in the header column (for sequence alignments longer than 250 amino acids) of the alignment and reexport the PDB coordinate files. At the page Renumbering PDB Files don't miss the How To button, which opens a slide show explaining how to use the PDB macros.

  Garlic, Free Molecular Visualization Program, Version 1.2:
Garlic is a free / open source molecular visualization program written for unix and unix clones, like linux. It is released under the terms of GNU GPL (General Public License). Garlic is capable to load and display more than one structure: the maximal number of structures which may be viewed simultaneously is limited by the system RAM. Rotations, translations and other operations are controlled by the numeric keypad rather than by mouse or special hardware (like dials). In addition to planar clipping (slab), garlic offers spherical and cylindrical clipping, as well as spherical and cylindrical color mapping. The only libraries required to compile and run garlic are the standard C library (libc), the standard X11 library (libX11) and the standard C math library (libm). At present (September 20, 2002) all other molecular visualization programs for unix (linux) require more libraries than garlic. The latest version of garlic is capable to create and edit protein structure and to attach a model of membrane to the structure of membrane protein.

  Ghemical:

Ghemical is a computational chemistry software package released under the GNU GPL. It means that full source code of the package is available, and users are free to study and modify the package. Ghemical is written in C++. It has a graphical user interface (which is based on GNOME), and it supports both quantum-mechanics (semi-empirical and ab initio) models and molecular mechanics models (there is an experimental Tripos 5.2-like force field for organic molecules). Also a tool for reduced protein models [1] is included. Geometry optimization, molecular dynamics and a large set of visualization tools are currently available.

Ghemical relies on external code to provide the quantum-mechanical calculations. Semi-empirical methods MNDO, MINDO/3, AM1 and PM3 come from the MOPAC7 package (Public Domain), and are included in the source distribution. The MPQC package (GNU GPL) is used to provide ab initio methods: the methods based on Hartree-Fock theory are currently supported with basis sets ranging from STO-3G to 6-31G**. The MPQC code is not included in the source distribution. In order to use the MPQC-based ab initio methods in Ghemical, you must first compile and install the MPQC program for your system, and then compile Ghemical using some specific settings that link the programs together. Ghemical also contains the OpenBabel package for import and export of many different file formats (as well as other tasks).

iMol is a free molecular viewer for Mac OS X operating system. iMol can load molecules using several file formats: PDB, XYZ, MOL2, HIN, CAR, ALC, BIO. The molecules can be saved as PDB, XYZ or BIO files (the BIO file stores all rendering settings, i.e. colors, lighting, orientation of molecules). iMol can easily handle both small and large molecules, it can load multiple molecules, move and rotate them independently.


   iMol uses OpenGL graphics to display molecules. The molecules can be rendered using various styles: wires, points, Van der Waals spheres, balls and sticks, strands, ribbon, cartoons, spring, tube, ladder. Individual atoms and/or residues can be selected using mouse or a simple selection query. There are several predefined color schemes available (e.g. residuum order, secondary structure, hydrophobicity), as well as custom colors. Also, different materials (e.g. plastic, metal, glass) can be used. Several rendering effects are available, including automatic rotation, motion blur, background gradient, perspective, and stereo projection (both side-by-side and red/blue anaglyph methods). Various rendering parameters can be fine-tuned. Atoms and residues can be labelled using names and numbers. The rendered images may be exported as a bitmap, as a PostScript file, or as a POV-Ray file.

   The program can meaure distances, angles, and torsional angles between atoms. Molecules can be superimposed and the RMSD (Root Mean Square Deviation) between atoms coordinates can be calculated. Additionaly, protein chains can be structurally aligned to detect regions of high structural similarity. iMol can load multimodel PDB files and display them as an animation (e.g. molecular dynamics trajectory). iMol supports QuickTime movie format for rendering the animations. The movies are efficiently compressed for web applications.


   iMol uses OS X Aqua user interface. Different options are placed inside a convienient mobile drawer. The iMol package includes several example files demonstrating full rendering potential and visualization capabilites.

  Jmol:   (English, Spanish, Dutch )
Jmol is an open source molecular viewer written in Java. It comes in two forms. There is a Jmol applet which, like Chime, displays the molecule within a web browser. Unlike Chime, you don't have to install a plugin -- Jmol arrives automatically with the web page and displays the molecule. Jmol's second form is a stand-alone application (like RasMol).

Because Jmol is written in Java, Jmol runs on a wide variety of operating systems (Windows, Mac OSX, linux, among others) and in all popular browsers (Internet Explorer, Netscape 4/6/7, Mozilla, Safari, etc.).

Jmol supports the RasMol/Chime scripting language. The Jmol applet provides a migration path for Chime-based web applications. Jmol includes a perl script which will automatically convert many Chime web pages.

The source code and java binaries are available from http://jmol.sourceforge.net and are covered under the GNU Publice Licenses.

  JMolEditor:
Java Molecular Editor (JMolEditor) is a program for displaying, analyzing, editing, converting, and animating molecular systems. It has intuitive interface and inbuilt help system. JMolEditor can be used also for the analysis to display molecular orbitals, electron densities and electrostatic potentials from the Gaussian. JMolEditor is written in Java, so it is a cross-platform application. System requirements: Java Virtual Machine (JVM) >= 1.5 and Java3d >= 1.3. JMolEditor supports submission of Gaussian jobs to remote computer using the ssh2 protocol. It can monitor submitted jobs and retrieve output files after job completion.

  MAGE:
MAGE (available for Windows, Mac, Unix, Linux, and now Java) is the freeware which first brought powerful macromolecular visualization to personal computers (in 1992). Over a thousand excellent tutorials on molecular structures are available in the form of kinemages (presentations that run in MAGE). MAGE has a number of unique and powerful capabilities not available in RasMol nor Chime. (Here is a brief comparision of MAGE vs. RasMol.)

There is now a capable Java version of Mage which runs on the Web with no plug-ins. The above page (by Martz) comparing Mage and Rasmol is nicely done in general. However, Mage has ribbons, backbone, ball&stick, etc. representations; kinemages are not scripts but are heirarchical, commented, 3D display lists; and making a simple kinemage is extremely easy, and its exploration is just as open-ended as in RasMol - it's only if you want to make a custom-crafted presentation that it gets "technical". Also, an important use of Mage now is to show all-atom contacts made by Probe (in real time, on Unix).

  Marvin Applets and JavaBeans:


Marvin Applets and JavaBeans can be applied in web or stand-alone applications for sketching or viewing structures, queries and reactions. Marvin Applets are free for free web sites. MarvinSketch and MarvinView applications are free for academic/home users or for anyone if accessed at the ChemAxon web site. These Java tools are useful in the front end of chemical database systems.

  Moilin:
Moilin is a molecular modelling program which can be operated in stand alone mode or as part of the Oscail package under PC-Windows. The download includes Mopac and Iconc. The program will also drive Tinker and PC-Gamess both of which are available free to academics. Thus calculations from molecular mechanics (including dynamics movies) to high level dft are possible. Moilin can generate plots of molecular orbitals from Mopac or Gamess. Moilin uses opengl graphics with high resolution hard copy (up to 2400 x 1800). Moilin interacts with the Oscail package which provides access to crystallographic software, file format conversion software, coordination polyhedra and Raster3D photorealism. Downloads include "on-line tutorials" and "on-line" help. Commercial users must obtain permission to use this software.

  Molecular Workbench:
Molecular Workbench is free, content-oriented molecular modeling software for use in education. Unlike the static ball-and-stick models, the Molecular Workbench software computes and visualizes the motion of ensembles of atoms in real time, in both 2D and 3D.

  Molecule Interactive Collaborative Environment:

The Molecular Interactive Collaborative Environment (MICE) is a Java/Java3D based molecular structure viewer. As a pure Java application, MICE will run without modification on any platform for which Java version 2 and Java3D are available. We have successfully run MICE on Windows 98/NT4.0, Solaris and Linux.

Using a simple form interface, users can users can create custom representations of any molecule in the Protein Databank (PDB), via a network-based scene generator (MSG) that uses MolScript to create VRML representations of the molecule of interest. Once loaded into MICE, the custom view can then be viewed interactively and queried using rudimentary scene interrogation tools.

As well as allowing a user to manipulate and examine a molecule locally, MICE can also share views of molecules across a network. In a collaborative session, multiple users at different geographical locations can view the same representation of the molecule of interest. Any user can take control of the session and alter the view of the molecule, with these changes being seen by all members of the collaboration.

  MolMol: MOLecule analysis and MOLecule display:
MOLMOL is a molecular graphics program for display, analysis, and manipulation of three-dimensional structures of biological macromolecules, with special emphasis on nuclear magnetic resonance (NMR) solution structures of proteins and nucleic acids. MOLMOL has a graphical user interface with menus, dialog boxes and on-line help. The display possibilities include conventional presentations, as well as novel schematic drawings, with the option of displaying different presentations in one view. The covalent molecular structures can be modified by addition or removal of individual atoms and bonds; the three-dimensional structure can be manipulated by interactive rotation about individual dihedral angles. Special efforts were made to allow for appropriate display and analysis of sets of (typically 20-40) conformers that are conventionally used to represent the result of a NMR structure determination, using functions for superimposing sets of conformers, calculation of root mean square distance (RMSD) values, identification of hydrogen bonds, checking and displaying violations of NMR constraints, and identification and listing of short distances between pairs of hydrogen atoms. MOLMOL is publicly available at no charge, and runs on UNIX and Windows NT/95/98/2000.

MolMol has been cited by over 500 scientific journal articles (search for "molmol" at highwire.stanford.edu). It ranks among the most popular free visualization programs, including RasMol (>700) and KineMages (>450).

  MolPOV 2:
MolPOV is a graphics file converter for MS Windows that reads Brookhaven Protein Data Bank format files and produces a ready-to-render input file for the Persistence of Vision ray tracer (POV-Ray). The PDB files can be from the Brookhaven PDB itself or from any molecular modeling program that can store structures in the PDB format. A POV setup dialog can be used to edit many of the basic scene features and rendering options. Molecules can be represented with spacefilling spheres, bond cylinders, or balls & sticks. Scene features that can be set in MolPOV include lighting, atom and/or cylinder texture, atom colors and finish, background, camera position, rendering size. POV-Ray input files to produce simple rotational animations can be constructed. In addition, the program allows launching of the POV program to view the rendering immediately.

  Patmos - a Molecular Screensaver:
click to view large screenshot Patmos is a screensaver that lets you display your favourite molecules on your Windows PCs. As with Santorini it can load XYZ, Gaussian cube or PDB files and will gracefully rotate them in a 3-dimensional view. If your system contains more coordinate frames or models then Patmos plays each frame sequentially as an animation. Settings such as rotation speed, positioning of light source, graphics quality versus CPU usage and much more can be controlled from the "Display Properties | Screensaver" applet in the Windows control panel.

  PDB2MGIF:
PDB to MultiGIF
Visualization of chemical 3D structures on the web comes with problems because the web browser cannot display chemical structures without the help of additional software. If you create a page with a 3D structure of a molecule and the visitor of your page does not use this special viewer software for displaying molecules it cannot get the whole information of the page which should be meditated.

PDB2MultiGIF takes the 3D structure and generates an animated image which can be displayed using any browser. Thus every visitor of your page can get the whole information. It has many controls including size, number of frames, speed and axis of rotation, and if you wish, you can supply your own view as a RasMol script.
