DISCOVERY STUDIO VISUALIZER 4.1 Editors Choice
Commercial-grade graphics visualization is available for free to all academic, government and commercial researchers through Discovery Studio (DS) Visualizer. With DS Visualizer, you can visualize and share molecular information in a clear and consistent way, and in a wide variety of industry-standard formats. You can also create high quality graphics. DS Visualizer runs on Windows 8, Red Hat Enterprise Linux versions 3, 4 & 5 and SUSE Enterprise Linux 10.
This is the successor of WebLab Lite from Accelrys. WebLab Lite though is still available from some sites online. There are several advanced features on Discovery Studio Visualizer including the ability to show ligand binding sites in proteins and create a surface around the ligand.
New to version 3.1 -- Functionality for building small molecules, and protein and nucleic acid structures
New Version 4.1
Chime is a plug-in program that allows you to view molecules in 3-D via Netscape or Explorer browsers. Although Chime is free you will have to register to download the version from MDL.
RasMol is a molecular graphics program developed at the University of Edinburgh. The software is intended for the visualization of proteins, nucleic acids and small molecules. The program has the ability to read in PDB as well as several other formats. For more information on RasMol visit the RasMol Home Page.
Swiss-PdbViewer is an application that provides a user friendly interface allowing to analyze several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts. Amino acid mutations, H-bonds, angles and distances between atoms are easy to obtain thanks to the intuitive graphic and menu interface.
ArgusLab Editors Choice
ArgusLab contains: An interactive 3D molecule builder that allows the user to build and manipulate complex structures; and, a rich suite of computational methods, both quantum mechanical and molecular mechanical, for calculating ground and excited states properties. The program is free for academic use
Mage requires the use of Kinemage files. There are presently available a large number of these files for both education and research purposes (see the Kinemage Home Page for more information. ) You can now run Kinemages on your home page using a Java enabled Mage. Because of the large number of Kinemage files available to the public this makes for an interesting teacher tool. See an example using the Mage Applet for the Fullerene Molecule.
JME Molecular Editor is a Java applet which allows to draw / edit molecules and reactions (including generation of substructure queries) and to depict molecules directly within an HTML page. Editor can generate SMILES or MDL mol file of created structures. You can download a copy at the JME Site.
Chemis3D, Molecular viewer is a Java Applet which renders virtual 3D molecular models within a Web document. It is specially designed for open interactive molecular visualization on the Internet or via an intranet. Chemis3D is a small applet (~30Ko) running well on any Java-enabled browser and requiring no specialized plug-in nor professional applications.
The TINKER molecular modeling software is a complete and general package for molecular mechanics and dynamics, with some special features for biopolymers. TINKER has the ability to use any of several common parameter sets, such as Amber (ff94, ff96, ff98 and ff99), CHARMM (19 and 27), Allinger MM (MM2-1991 and MM3-2000), OPLS (OPLS-UA, OPLS-AA and OPLS-AA/L).
This software is FREE to ACADEMIC users. Commercial users must obtain permission for its use.
This Windows software provides an integrated high quality system for building and modelling molecules (Mopac and Iconc are included) and the system drives PC GAMESS and Tinker. The crystallographic software can solve, refine and examine small molecule crystal structures. The pictures produced range from high quality HPGL to photo realistic rendered 3D. Rendered movies are effective and easy to make using RASMOV. Software for Powder pattern simulation and the detection and display of voids is also available.
YASARA is a molecular-graphics, -modeling and -simulation package for Linux and Windows.YASARA is powered by PVL (Portable Vector Language), a new development framework . PVL allows you to visualize even the largest proteins and enables true interactive real-time simulations with highly accurate force fields on standard PCs. The initial level stage can be downloaded free.
JMol Editors Choice
Jmol is a free, open source molecule viewer written in Java. It runs as a standalone application and as a web browser applet. Jmol is a collaboratively developed visualization and measurement tool for scientists and educators. New features being added on an ongoing basis. Users are encouraged to modify it to fit their needs and to contribute their changes to the project. JMol is a Chime/Rasmol replacement.
For Jmol applications See 3D Molecules using Jmol Software
For Jmol downloads see here.
Now Jsmol runs on tablets and works better on the Mac.
