Easy instructions for creating tutorials like this one.

Download for faster/smoother operation. If you have a copy of this tutorial on your computer's hard disk, you can display it in Netscape without an Internet connection. Running the tutorial over the Internet will be slow, therefore it is STRONGLY recommended that you do download and run it locally when projecting to a class.

Improved versions of this tutorial and new animated tutorials will be posted on the Animated Tutorials Page at the RasMol Home Page, or on the UMass Chime Resources Site.

Version History

February 27, 1998, version 1.21. A correction thanks to Judith Voet (Swarthmore): only one histidine nitrogen contacts the iron in heme. The other histidine H-bonds to oxygen or, in deoxyHb, sometimes to water.
February 17, 1998, version 1.2. Added font size control. Utility menu enhanced. Color scheme menu added. Excess space at bottom of right frame removed (unless in continuous play mode, when it is needed).
January 24, 1998, version 1.1. Made compatible with Navigator 4.04 and Chime 2 under Windows 95.
September 22, 1997, version 1.01. Fixed bug (missing alpha helix PDB file).
September 21, 1997, version 1.0. (adapted by Rashie Athukorala and Eric Martz from the RasMol "movie" script by Eric Martz, March 1996).
