Chime and Rasmol Links
Rasmol is a program for viewing macromolecular structures coded in the Brookhaven Protein Data Bank (PDB) format. Chime is a plugin for Netscape 3.0 which uses many of the Rasmol commands to allow viewing of PDB files (and many other formats) in the browser.
This course uses Chime-based tutorials extensively, and students are advised to download the requisite software. All PDB files used in Chime tutorials can be downloaded using the File option under the Chime menu. These can then be explored in greater detail using Rasmol.
Download Rasmol from the Rasmol Homepage.
