RasMol and Protein Explorer

RasMol and Protein Explorer http //www.umass.edu/microbio/rasmoE and http //molvis.sdsc.edu/protexpEfrntdoor.htm, respectively. 

Extensive help is displayed automatically for every menu operation. For example, if you COLOR Charge, you are told how and where to calculate the charge or pi of your protein on-line. If you SELECT Nucleic, there is a button to help you distinguish DNA from RNA. 

PE has molecule-specific links to external resources, for example to visualize specific oligomers or virus capsids, or to color by evolutionary conservation or mutation. 

In amount of program code, it now rivals the size of RasMol. (Chime has well over 100,000 lines of C++.) 

Protein explorer is one of the most widely used visualization tools for protein structures. Protein Explorer is free software for visualizing the three-dimensional structures of protein, DNA, and RNA macromolecules, and their interactions and binding of ligands, inhibitors, and drugs. Protein explorer is easy to use, free, and widely used. It can be used be novice users as well as experts. The RasMol website has been visited by over 250,000people from 115 countries.
