Video Tutorial for NCBI's Cn3D Molecular Viewer
Cn3D is free molecular viewer software available from NCBI, a division of the National Library of Medicine. This video tutorial (2 minutes, 21 seconds) illustrates how to use Cn3D to customize and annotate the appearance of a known molecular structure. It also briefly discusses basic searching in Entrez Structure, and the PDB (Protein Data Bank), where all protein data is archived.
Cn3D also has many additional capabilities, which are described in traditional web-based tutorials at the NCBI website.
