60 minute Rasmol

This two page Rasmol tutorial introduces this powerful program for viewing molecules. The tutorial uses the structure ofFN7-10, the cell adhesion domain of fibronectin, as an example. Instructions are provided to get the Rasmol program, get the PDB file for FN7-10, display and rotate the molecule, identify and color specific aa's, etc.

The reference for the structure of FN7-10 is

More: Check out more Rasmol tutorials, for some different approaches, a wealth of neat details. See also David Hackney's Rasmol tutorial

PMCID tutorial. March 2009. This explains how to enter PMCID numbers in PubMed Central to comply with the new requirements for listing references for NIH grants. Explains what you do and don't have to do. I have an EndNote Style that will print the PMCID, but I haven't figured how to post it here. Contact me by email if you want it. h.erickson@cellbio.duke.edu
